As Windows users, control panels and Settings applications can feel their limited functionality. If you want to have full and absolute control over your network, which means accessing everything the operating system must provide, you will have to start using command prompts. Never used a command prompt? Don’t worry.Using it is as simple as typing the commands you’ll see below. It’s not hard. We’ll tell you everything you need to know at first. However, if you are still unsure, check out our command prompt beginner guide.
Ping is one of the most basic but useful commands you might know. It tells you whether the computer can access a target IP address or domain name, or, if so, when the data is returned again.
Sample usage and output:
This command works by sending multiple packets and seeing how many of them are returned. If some of them don’t come back, it’ll tell you (lost). Packet loss leads to poor performance of games and streaming media, which is a good way to test.
By default it sends 4 packets, each one waiting 4 seconds before timing out. You can increase the number of packets like this:
And you can increase the timeout duration like this (value is in milliseconds)
Tracert stands for Trace Route. Like ping, it sends packets as a solution to any network problems you may encounter, tracking the routing of packets when packets jump from the server to the server.
This command outputs a line-by-line summary of each hop, including the delay between you and the particular hop and the IP address of the hop (plus the domain name, if available).
Why do you see three delayed readings per jump? Because tracert sends three packets per hop in case one of them is lost or takes too much time without representing your real delay. The average of three is the best practice.
Pathping is similar to tracert, in addition to more information, which means that execution takes longer. After sending the packet to the specified destination, it analyzes the route used and calculates the packet loss by hops.
Sample usage and output:
Ipconfig is probably just the most commonly used network command on Windows. It is not only useful for the information it provides, but also can be combined with several switches to perform certain tasks.
Sample usage and output:
The default output shows how each network adapter on the system and how they are resolved. The IPv4 address and default gateway details under the wireless LAN adapter and the Ethernet adapter section are the most important.
Use this switch to flush your DNS cache:

One of the most time-tested rules for network design is this: Switch wherever you can, route wherever you must. In essence, networks should be deployed by utilizing switching technology wherever it is possible, interconnected by routers only wherever it is required. Of course, the definition of “required” could vary a great deal as well as change over time as different network fads come in and out of the fashion.
A good start would be to break up networks into different zones, separating user access networks, whether they are staff or guest, from data centers. These separations are considered to be logical points for routers and, in some cases, firewalls. Even though many users would spread through a building might look similar to many servers in a data center, the networks would have very different performance as well as reliability requirements. By creating a clear separation, network managers would be able to focus on designing networks that are fit for purpose rather than over-engineering or under-engineering. Before we discuss about the Distribution and Aggregation Layer, let me make you one thing very clear, that there are lots of things needed to be considered in networking, which you cannot just read and acquire, you are needed to go through immense training, which you could obtain through the training module offered by the SPOTO.The Distribution And Aggregation Layer: In small networks of a few hundred users, edge switches could be connected redundantly directly to the core switch or router devices. However, for larger networks, an additional layer of switching, which would be called the distribution layer, aggregates the edge switches. The main goal of the distribution layer is simply to cable the reduction and network management, taking the many uplinks from edge switches as well as aggregating them into higher speed links.
If edge switches are being chosen so that each wiring closet has only a single redundant uplink, then the distribution layer is generally to be placed next to the network core, with a minimum of two devices connecting to each wiring closet
However, if the edge switch topology creates multiple redundant uplinks As for illustration, if non-stacked switches are selected or if there are an enormous number of connections in each wiring closet, then an aggregation layer which is really just another distribution layer can be placed in each wiring closet. The aggregation layer connects to the uplinks of the edge switches and is uplinked to the distribution layer toward the network core.
In small networks, uplink speeds of about 1Gbps might even become satisfactory, depending on the total number of user devices which would be served by each wiring closet and the application demands on the network. Wiring closet uplink speeds of greater than 10Gbps would be required only in very unexpected cases.
Aggregation as well as distribution layer switches which are generally selected over edge switches for their greater reliability as well as the larger feature set. While the aggregation or distribution layer should always be redundant, devices at this layer would be offered nonstop service, like in-service upgrades and hot-swap fan as well as power supply modules.
Aggregation and distribution layer switches which would also have more stringent performance requirements, which would be including lower latency and larger MAC address table sizes. This is considered because they might be aggregating traffic from thousands of users rather than the hundreds that one might find in a single wiring closet.
These are some details about the Aggregation Layer n Networking, but if you wish to have more knowledge regarding the same, you could do it by gaining the training courses that are offered by the SPOTO. They are the best when it comes to the courses related to Information Technology and lots more.

If you’re searching for a safe, powerful, tech-savvy internet solution, you may have discovered both VPN and MPLS technology. VPN stands for Virtual Private Network, while MPLS stands for Multi-Protocol Label Switching. What's more, MPLS and VPN are two parts of the CCIE RS Lab certification exam, and you must master two technologies so as to pass the exam.
These are two different systems for keeping you more anonymous and secure online, as well as improving connection speeds.
Since both types of networks are quite complicated, it can be difficult to understand exactly how they work or what distinguishes them from each other. If you want to figure out if you should get an MPLS or a VPN, you need to know which system will keep you safest and provide the best service.
Fortunately, our experts are here to help you sort out this issue and find out whether MPLS or VPN technology is right for your needs.
What Is the Difference Between MPLS and Internet?
There are a few key differences between the way an MPLS and standard internet protocols work.
To understand these differences, you first need to know about packets. When you send and receive information online, it comes and goes in packets. These segments of information travel throughout various entry and exit points to transmit and receive data.
Usually, these packets must go through multiple layers to access the internet. They start on computers (Layer One), move onto networks (such as LAN – Local Area Networks, or WAN – Wide Area Networks, which would be Layer Two), and then go onto the internet. Once they’re on the internet, they typically move through several more layers before finally reaching their destination.
While packets move throughout Layer Two of this system, they travel from router to router (or between similar devices). In order to get from place to place correctly, each router looks up the IP (Internet Protocol) address for the next router the packet needs to travel to.
The router then sends the packet there, where the next router looks up the next IP address, and so on, until the packet reaches its target.
Each router performs this process independently of the others. The midpoint routers between the computer and the packet’s destination are called “next-hops,” since the information goes there next, bouncing along on its journey.
Looking up IP addresses is done on Layer Three of the internet, beyond computers (Layer One) and networks (Layer Two). The process of looking up these IP addresses can take some time for routers.
As the data bounces from one router to the next, the lag time required to retrieve the IP addresses can add up.
Plus, perhaps more importantly, using this conventional IP routing system may not be anonymous, leaving your data open to breaches and hacks. Hackers, targeted advertisers, governmental agencies, and more prying eyes could spy on your own personal IP address during this process.
Multi-Protocol Label Switching (MPLS) changes the way packets travel. Instead of hopping from one router to the next, a packet leaves a computer, and then the very first router conducts just a single lookup to find the end router.
This router then creates a list of directions for the packet so it knows which routers to bounce between, labels it with these guidelines, and sends it on its way.
From there, it goes from router to router as it normally would, but because the directions are already laid out, none of the subsequent routers need to look up or calculate any IP addresses. When the packet reaches the end of the line, the last router removes the packet and delivers it as usual.
MPLS labeling is similar to a physical map or GPS directions for your car. It tells the packets exactly where to go in advance, which speeds up the network and minimizes potentially insecure IP lookups.
Because the packet is labeled between its transmission from the network (Layer Two) to the internet (Layer Three), MPLS is sometimes called a “layer 2.5 networking protocol.”
MPLS does have some notable limitations, however. Since each router will not use IP protocols to calculate its packets’ next stops, MPLS systems must be configured with a clear LSP, or label-switched path, from router to router to router to destination.
MPLS also requires an LSR, or label-switch router. This device decodes the label on the packet to direct it properly.
Ultimately, for MPLS to work, the entire router configuration has to be set up in a very particular way.
It works best on internal systems, like home LANs (Local Area Networks) or business networks in a single office. Supporting wider, broader, international MPLS would take a lot more equipment and expertise, making it somewhat expensive.
Essentially, an MPLS setup needs its own unique network of routers and methods for them to communicate with each other.
If you want to compare MPLS with VPNs, you’ll also need to know how VPNs work and what they do. As we mentioned above, VPN stands for Virtual Private Network. This system changes the way packets travel to and from the internet in two distinct ways.
First of all, data sent through a VPN is protected through a process called VPN tunneling. Packets of information that travel through a VPN are disconnected from other internet traffic – they travel in virtual tunnels.
This process is called encapsulation, which separates VPN packets from others moving on the same network.
As part of tunneling, data relayed through a VPN is also encrypted, so it’s wrapped in layers of code, which can then be decoded when it arrives to its destination.
Different VPNs use different types of encoding protocols, such as PPTP, L2TP, SSTP, IKEv2, and OpenVPN. These all help protect your information and keep you anonymous online.
Secondly, a VPN routes the data it transmits through its own servers before this information reaches the rest of the internet.
This makes it look as if your internet activity is coming from the VPN’s servers rather than your own, which can both safeguard your privacy and allow you to access geoblocked content, such as Netflix or HBO. You get to choose which IP address you want your data to appear to come from.
When you use a VPN, all your ISP (Internet Service Provider) knows is that you’ve connected to a VPN. This configuration makes it much harder for anyone to track or steal your data.
Some VPN providers even have a no-logs policy, which means even they don’t store your data. (We’ll discuss how that works later in this article).
VPNs also help enhance Tor and torrenting functionality. Many VPN providers set up their networks specifically to optimize these types of internet activities. For more information, check out our list of the best VPNs for torrents in 2019.
In short, a VPN offers a set of servers in different locations that you can route your internet traffic through, which helps hide your IP address. They also create special tunnels for your packets to travel through and encrypt your data, making it much harder for anyone to hack or spy on you.
What Is the Difference Between MPLS and VPN?
Both MPLS and VPN systems are designed to alter the way you connect to the internet and help you maintain your privacy online. The primary difference between the two is how they go about that.
As we’ve explained above, MPLS provides a labeled map for your packets of data, allowing them to travel more quickly and privately between routers, since it eliminates the need for multiple IP lookups.
In contrast, a VPN uses IP lookups, but it protects your personal information by sending it through a virtual tunnel, encrypting it, and routing it through a VPN server before it reaches its destination.
Is MPLS Faster Than VPN?
Whether or not MPLS is faster than VPN depends largely on the particular factors of each, so there is no clear, consistent answer to this question. However, there are certain trends.
Conventionally, MPLS is designed more for speed than a VPN is. The labeling function in MPLS could theoretically speed up an internet connection, since each individual router does not need to perform an IP lookup.
In addition, MPLS networks may be smaller and more contained than VPNs’, which could also speed them up in comparison.
However, since regular internet speeds have been getting faster and faster, and since bandwidth is getting less expensive to purchase, MPLS may no longer offer any significant speed advantage.
Furthermore, some information technology professionals argue that labeling cannot really offer notable speed increases. They claim that MPLS adds a layer of complexity through labeling and requires the same types of lookups as traditional internet protocols, just in advance.
In contrast, VPNs may slow down internet traffic slightly, since every packet has to be encrypted and routed through an additional VPN server before it reaches its end point. However, even despite these additional steps, some VPNs actually still speed up traffic.
This is because ISPs often “throttle” traffic, meaning that they intentionally slow down certain types of activities, such as torrenting. When you use a VPN, all an ISP can see is that you’re using one, so they can’t lower your speeds. In this way, using a VPN can improve your internet security, unblock geo-restricted content, and boost your speeds.
Of course, not all VPNs improve connection speeds, so a given VPN may be slower than an MPLS. However, in this case, an MPLS system’s speeds probably just barely outpace a VPN’s. The difference may not even be noticeable.
Regardless, many users find that it’s worth slightly slower speeds to enjoy the many advantages of VPNs over MPLS and other systems.
For users who want to enjoy blazing speeds and all the benefits of VPNs, we recommend ExpressVPN.
Is MPLS More Secure Than VPN?
One of the primary goals of both MPLS and VPN systems is safety, but which system is actually more secure?
MPLS is by definition a private network, with its own infrastructure and routing protocols. Internet traffic moves through it according to its labeling system, only interacting with the traditional internet framework at its edges.
Since it reduces the number of individual IP lookups necessary to go online, MPLS may be less vulnerable to certain types of hacking.
However, if part of the equipment for MPLS wasn’t set up properly, especially at the “edges” of the network where routers do perform IP lookups, your data could be at risk.
Furthermore, since MPLS traffic is not encrypted, if someone did find their way into the private network, users’ privacy might be at stake.
All it would take is one untrustworthy person or one particularly skilled cybercriminal to break through MPLS security. Once the hacker got in, he or she would be able to view all of your passwords, bank data, and any other sensitive information, since it isn’t encrypted.
Some MPLS providers add on encryption and/or other security protocols to keep your data safer, but this is not necessarily the default. The safety of your data might depend on the additional (and likely more expensive) features that your particular provider offers.
In contrast, VPNs use several layers of defense to protect your private information. Since your data is routed through VPN servers in remote locations through virtual tunnels, it would be difficult for a hacker to get to it.
However, even if a cybercriminal did break into your VPN, he or she wouldn’t be able to make sense of your data, since it’s encrypted.
In addition, some VPN companies provide additional layers of security for their users. For example, many VPN companies boost their security by implementing no-logs policies.
Basically, even though hackers, government agencies, and other prying eyes usually can’t access your data when using a VPN, the company that provides the VPN might be able to.
This could put your data at risk if the government or any other outside entity ever pressured the VPN to share its users’ information and activity. Hackers who got into the VPN’s central servers and databases might also be able to view data stored there.
Logs of your information could also interfere with your privacy and safety if the VPN company itself decided to use your data in an unsavory way, such as selling it.
VPN providers that have committed to no-logs policies promise that they will not store user data. This means that even if the government comes knocking, a hacker gets into one of their databases, or someone untrustworthy at the VPN company wants to sell your data, your information simply isn’t there to be exploited.
If you want an all-around excellent VPN with an outstanding no-logs policy, we advise you to try NordVPN. It’s the top VPN on our site for a reason. NordVPN does not monitor, retain, or store any of its user logs or data.
Other companies build a kill switch into their VPNs to keep users safer.
This feature automatically disconnects from the internet if your VPN loses connection, preventing your real IP address from ever being revealed. If you’re looking for a great multi-device, high-speed-streaming VPN with a kill switch, we suggest you try CyberGhost VPN.
When it comes to security, VPNs are typically safer and more private than MPLS systems. While MPLS systems are private, your data could be extremely vulnerable if they were ever hacked, since they don’t typically include encryption.
Even beyond standard VPN encryption, tunneling, and routing protocols, many add on extra defenses, just to keep your data as safe as possible.
MPLS vs. VPN Costs
You probably don’t want to spend more than absolutely you need to for a secure, fast, reliable connection. When it comes to price, MPLS systems usually cost much more than VPNs.
Both services require purchasing and maintaining sophisticated equipment, providing customer support as needed, and other valid costs, which can affect their prices. However, while the costs of other types of internet infrastructure and features have generally come down, MPLS has only slightly decreased in price over time.
MPLS is priced by Mbps (megabits per second) per month and can be on the expensive side. Meanwhile, VPNs are usually much more budget friendly, and some are even free (although we’d caution you to carefully select a free VPN from our list and look out for any hidden costs associated with this type of service).
Of course, the particular costs of any given MPLS or VPN depend on a variety of factors, such as their specific features, location, size, and more. Generally speaking, however, when it comes to price, VPNs are clearly superior to MPLS systems.
If you’re looking for an extremely affordable VPN that still offers the standard features you need, we recommend you take a look at our list of the best cheap VPN providers. These VPN provide you with excellent security, speed and streaming media at a reasonable price. When MPLS and VPN Meet.
Although MPLS and VPN are often competitors, they can also be combined. The cloud version of MPLS labeling can be integrated with VPN systems. This could produce an even stronger, safer system.
Since it can often lead to better bandwidth and faster speeds, an MPLS VPN hybrid may be best for large businesses or individuals who need to perform bandwidth-heavy activities with minimal delays. For example, companies that regularly run VoIP and video conferencing apps may benefit from MPLS VPN.
However, as with traditional MPLS, MPLS VPNs can be much more expensive than a typical VPN. These systems can be especially costly if they need to transmit information across large distances, as is often the purpose of VPNs (unblocking geo-restricted content, sharing files between international offices, etc.).
For these reasons, we recommend looking into an MPLS VPN if:
You’re willing to pay additional fees for more bandwidth.
Your network is local rather than international.
It’s crucial that you experience little or no delays.

Obviously, to become a Perfect CCNA Collaboration, you would first require gaining the certification. Below mention is the guide about how to achieve the CCN Collaboration Certification easily. We will begin by gaining knowledge about the CCNA Collaboration Certification. Also, for better results, it is recommended to gain the training with a good training institute, like the SPOTO.
CCNA Collaboration Overview:
This certification program is basically designed for the network video engineers, collaboration engineers, IP network and IP telephony engineers who are willing to develop and advance their skills of collaboration and video in line with the convergence of voice, video, data applications as well as mobile applications, the Cisco CCNA Collaboration certification is considered to be a job-role-focused on the training and certification program. It would allow the candidates to maximize their investment in their education, and increase their professional value by giving them the skills to help their IT organization meet increased business demands resulting from these transitions of technology.
Now, let’s discuss the exams, so the candidates pursuing this certification would be required to go through the following exams:
The Implementing Cisco Collaboration Devices otherwise known as 210-060 CICD exam is going to tests the knowledge of the candidate regarding Cisco Unified Communications (UC) solutions. A candidate would be tested on knowledge of administrator as well as end-user interfaces, mobility, and telephony features, and finally Cisco UC solutions maintenance.
The Implementing Cisco Video Network Devices otherwise known as 210-065 CIVND exam is going to tests the knowledge of the candidate regarding skills of implementing various Cisco Video endpoints in converged Cisco visual infrastructures. It would also be testing the ability of the candidate's to implement and troubleshoot Cisco Unified Communication as well as Collaboration, TelePresence, and Digital Media Player in diverse Cisco business video solution architectures.
So, as we have gained the knowledge about the CCNA Exam, and their topics, let’s move on to out the last step, which would tell you about how to obtain a CCNA Collaboration Certification.
The first step towards successfully achieving this certification would be to create a good and reliable plan for the preparation. You are required to cover all the topics which would be included in the exams. Take a print out of the syllabus and plan your study accordingly.
Execute the Plan:
After Planning, comes implementation. Yes, just preparing a plan isn’t going to finish your work. During the preparation as well as when you are going to appear for the exam, time management would be considered quite crucial. You should study consistently according to your plan and retain in your memory, whatever is learned.
Give Importance to Details
Learning the theory by-heart doesn’t go to help you in clearing the exam. You need to understand how things are done in Cisco. Sometimes, Cisco works differently than their basic scenario. So, get to know about the procedures which are being used in the Cisco environment. Cross-check every minute detail so as to ensure that you have not missed anything, in your study.
Practicing is going to make you perfect. You should practice whatever you have learned. It is very essential to reinforce the concepts in your mind. You might have to practice every single detail in order to acquire enough confidence for facing the exam. The book will just give you an idea of the basic theory. If you wish to find out whether it is true or not, you should have to go through the practical work. This would give you some extra knowledge in addition to the theoretical knowledge, which you acquire. So, if you follow this guide, and also, get yourself enrolled in the SPOTO Training Modules for CCNA Collaboration Certification, you would easily have your hold on this certification in no time.
Layer 3 Switching Overview
In order to understand about Troubleshooting the Layer 3 switching which would be using the switch router, it would be better to have an overview of the same. It would show how a switch router would fit into the network, the architecture of the switch router, as well as the course of a Layer 2 and Layer 3 packet through the switch router. Also, it would include a list of Layer 3 switching software features with brief descriptions of selected features. Before we discuss the troubleshooting the Layer 3 Connectivity of CCIE Data Center, you would be needed to know that you are needed to have a hands-on practice to acquire the skills of Troubleshooting much faster and easier. You could join the courses and mock lab sessions which would be provided by well-reputed organizations like the SPOTO.
A Layer 3 switch router would be performing the following three main functions:
Intelligent network services
Layer 3 Forwarding:
By using CEF, each of the line cards is going to maintain a FIB (Forwarding Information Base) table which would be downloaded from the switch processor. Any changes that would be made to the route processor routing table, caused by additions or deletions of routes or route flaps, are going to be updated in the central FIB, which in turn would be updating the line card FIBs. This means that, at all times, all line cards would have a correct map of the network topology.
Troubleshooting Layer 3 Connectivity:
Once you have Layers 1 & 2 workings, your show interface command would show the line is “UP & UP”, it is now time to move on to layer 3, which would be the OSI Network layer. The easiest thing to do here would be to see if layer 3 is working is to ping to the remote side of the LAN or WAN link from this router. Make sure you ping as close as possible to the router to which you are trying to communicate from one side across to the other side.
The following would be recommended taking this interface configuration and comparing it, side by side, with the remote WAN connection so as to ensure that they are the same. You need to ask yourself questions like:
Are these interfaces present on the same IP network?
Would these interfaces have the same subnet mask?
Are there any access-lists (ACL) which would be blocking your traffic?
Would you be able to remove all optional IP features to make sure that the basic configuration works before adding additional features that could be causing trouble?
Let’s suppose that now you are able to ping across the link, from one side to another. While that would be considered as a great sign, it doesn’t always mean that everything would be considered as “fixed”. You might still not be able to communicate from a client on the LAN of one router, to a client present on the LAN of another router, due to reasons like improper configuration of IP routing protocols.
It doesn’t end here, there are lots more thing which the candidates are needed to learn for the Troubleshooting the Layer 3 Connectivity of the CCIE Data Center Module. Consider it just a pinch of everything which would have to learn while appearing for the CCIE DC Certification. But worry not! To gain more hands-on training and practice sessions as well as help related to the written exam, acquire the courses which are offered by a well reliable training institute like, the SPOTO.
Hot Standby Routing Protocol otherwise known as HSRP is considered to be a Cisco proprietary protocol that would be allowing two or more routers so as to work together for representing a single IP address for a particular network. HSRP, as well as VRRP (Virtual Route Redundancy Protocol), are considered high-availability network services that would be allowing for almost immediate failover to a secondary interface when the primary interface would become unavailable.
HSRP is considered to be a fairly simple concept that would have worked by having one router within an HSRP group which would be selected as the primary or active router. That primary would be handling all routing requests while the other routers within the HSRP group that would be simply waiting in a standby state. These standby routers would be remaining ready to take on the entire traffic load if the primary router would become unavailable. In this scenario, HSRP would be providing high network availability since it routes IP traffic without having to be dependent on a single router.
The hosts that would be using the HSRP address considering it as a gateway that would never know the actual physical IP or MAC address of the routers in the group. Only the virtual IP address which was created within the configuration of the HSRP along with a virtual MAC address which would be known to other hosts on the network.
Basic HSRP Configuration
For this scenario, you have to use a topology that would be consisting of just two routers. Keep in mind that one or both of these routers would be multilayer switches like a 6509 or 3750 as well. But just for this discussion let us just refer them as routers.
Controlling the Active HSRP Router
There are more HSRP values that you are going to need to change from time to time so as to ensure the complete control over your network traffic. As for example, what if we would be wishing R1 to be the Active router instead of R2? To force a particular router so as to be the active router in an HSRP group you are going to need to use the priority command. The default priority is supposed to be about 100. The higher priority would be determined which router is going to be active. If both routers would be set up to the same priority, the first router to come up would be considered as the active router.
Keeping the Active Router Active
In the scenario which is mentioned above, if R1 fails, R2 would be becoming active. This is perfect! But, if R1 comes back up and returns to service, R2 would be continued to stay active. This might not be a preferred behavior. There are times when you might be always wanted R1 to be in an active state in the HSRP group. Cisco would provide a way to getting used to controlling this by utilizing the Preempt command. Preempt would be forcing a router in order to be active after recovering from a failure.
Advanced HSRP Configuration – Load Balancing
So now you would be able to see how great HSRP is and how it would be allowing us to have high availability between multiple routers for a single network. But the standby routers wouldn’t be doing anything and are just sitting there! It is going to be depending on the model router that you would be utilizing, this could be a lot of money just sitting idle.
In order to solve this problem, we could configure HSRP so as to be load balanced between routers. This isn’t going to help us with a single HSRP group, but for multiple HSRP groups, we could just spread the load and have each HSRP group to remain active on different routers. By configuring several HSRP groups on a single interface, load balancing of HSRP could be achieved.
If you wish to learn more about configuring the HSRP on Router, all you need to do is to join the courses, offered by the SPOTO and learn it all through their expertise training modules.
Introduction to CCIE RS online course
CCIE Routing and Switching certification Course would be designed for network professionals, managers, senior network engineers and architects who are considered to be responsible for implementing as well as troubleshooting today’s complex converged networks in an enterprise networking environment.

In order to gain the CCIE Routing and Switching Exam, candidates need to clear the below-mentioned exams:
CCIE Routing and Switching Written Exam:
The Cisco CCIE Routing and Switching Written Exam are going to validate those professionals who would have the expertise to: validate, configure, and troubleshoot complex enterprise network infrastructure; as well as understanding about how infrastructure components would be interoperating; and translate the functional requirements into specific device configurations. The exam would be closed book and thus, there would be no outside reference materials allowed in the exam.
CCIE Routing and Switching Lab Exam
The CCIE R&S lab exam is considered to be an eight-hour, hands-on exam which would be requiring you to configure as well as troubleshoot a series of complex networks to given specifications. CCIE R&S Lab exam consists of three modules. The Troubleshooting module would be consisting of 2 hours. If desired, the candidates would be able to extend the Troubleshooting module's time by borrowing up to 30 min from the time period of the Configuration module. Note that, the total Configuration module time would have to be reduced by the extra time spent in the Troubleshooting module. Say for example, if the candidate early finishes the Troubleshooting module, the unused Troubleshooting module’s time would be added to the Configuration module’s time, ensuring that the total lab exam time doesn’t exceed 8 hours. The Diagnostic module would be fixed in duration which would be about 30 minutes.
Why Choose SPOTO for CCIE R&S?
SPOTO CCIE R&S dump or practice exam would be covering all of the exam topics which you would need to prepare the exam. The practice exam comes with CCIE R&S exam accurate questions and answers which are verified by experts.

Candidate should be Graduate in any stream to go for CCIE Collaboration Certification. A CCIE Collaboration candidate should have knowledge of technologies covered in CCNA, CCNA Collaboration and CCNP Collaboration Certifications to begin with CCIE Collaboration exam blueprint. Our CCIE Collaboration Integrated course covers all the training required to successfully achieve this Certification. This program would be considered to be designed in such a way that placement is automatically assured after successful completion of this program. New CCIE Collaboration Certification would be having some add on technologies such as Video processing etc, which would again take one more month to complete the course after current CCIE Collaboration syllabus. New CCIE Collaboration Certification would be considered to be more interesting and would be included in the new upcoming technologies, which will benefit students for a great career.
Disadvantages of Free Dumps:
When you would be utilizing the free exam dump, you really don’t have much to engage with as it would only the repetitive action of memorizing questions and answers. You wouldn’t be actively retaining information from simply reading through questions and drilling the correct answer into your brain. Because free braindumps don’t explain the reasoning behind answers, which you could gain in the study dumps which are provided by SPOTO, as along with these study dumps, they also provide you the expert training, which would be given through their expert trainers.
When you’re preparing to take an exam, you don’t just require passing the exam. You would also need to be able to apply for each and every concept you would have learned in preparing for that exam so that you could do your job to the best of your ability. The primary goal of taking an exam shouldn’t just simply pass it but in order to make steady improvements in the work that you do.
Zero Quality Control:
Free Dumps would provide absolutely no form of control, so you don’t know whether you’re are utilizing a reliable or correct exam dump. The questions, answer options, as well as answers could be completely incorrect, and there would be no way for checking them until it would be too late.
Actual certification questions would be needed to go through rigorous research, design, as well as testing before they end up in a question bank. While with Free exam dumps, there’s going to be no way for telling where the information would be coming from, or how old or accurate it might be. You want the best study material available, and there’s absolutely no way to guarantee that the free exam dumps would be able to meet those criteria. Instead, it is recommended to choose the prep courses, which would be offered by paying the little price and which comes up with the passing guarantee as well as tutor assistance, like it is offered by the SPOTO.
Advantages of SPOTO's dumps
On the basis of the feedback acquired by the candidates who would be around the world and their expert’s fifteen-year research on Cisco exam, SPOTO update dump at the very first time. The information which would be provided by the SPOTO would be able to keep up with Cisco, therefore when the exam is ready, they would provide valid exam questions to candidates. They would not only provide the valid questions but they also provide simulated real exam practice system for candidates so they could adapt themselves to the real exam both on content and on the environment.
When it comes to IT certifications, Cisco Systems is considered near the top of the category in terms of interest, perceived value as well as size and heft of its overall program. The Cisco Certification pyramid shows a well-elaborated family of credentials that are available at many career and complexity levels, where both Architect and Expert certifications most notably, the Cisco Certified Internetwork Expert, or CCIE would be remaining evergreen credentials and in high demand, with lots of cachets, and considerable income-generating power. Below mentioned are some sites, which you could rely on to learn about the Cisco Certification. But along with these practice sites, you also need to have good training, which you could gain it through the SPOTO.
1. The Cisco Learning Network:
Cisco operates a formidable training as well as certification operation, both online and in person. The online portion is called The Cisco Learning Network or, more unofficially, Cisco Learning. Here, you could be navigated to the individual credentials as you see fit, but you could also tap into a huge volume of supporting and surrounding information.
Whether you would be looking for resources to help you to obtain that first Cisco certification or you are a seasoned professional which would be seeking to advance in order to the next Cisco certification level, MeasureUp is definitely considered is worth exploring.
3. Cisco Press:
Cisco Press offers an amazing collection of certification preparation materials. CCNA self-study resources would be illustrating, you could find all kinds of materials for the enormous majority of Cisco certifications at the company's official press site. Cisco Press not only would be offering a full-length study guide, but also the software simulators, flash cards, video training, and even practice tests.
4. CCNA Cert Prep at Celtic Rover
The Celtic Rover CCNA pages would be offered to some great resources for IT professionals preparing for Cisco's CCNA exam. You would be finding lots of great information in order to dig into for the various CCNA exams. This material would make a great supplement to the candidates who are preparing through Cisco Press CCNA exam cert prep books.
5. CCNP Certification Prep at CCNP Guide
As with Celtic Rover for CCNA, there's a lot of good stuff that you could learn at CCNP Guide which would help you out to bone up for the various professional level CCNP exams, especially for those who are on the Routing and Switching track.
6. Cisco Lab Kits
The higher you climb up the Cisco certification pyramid, the more the importance of hands-on access to the hardware increases. That's why at least half of Cisco CCNP candidates as well as those who are pursuing CCIE, purchases their own gear upon which they are going to practice on. And in the case of the CCIE, Cisco pros would be spending a great amount of time with the hardware so as to prepare for the infamous CCIE lab exam.
7. Cisco Virtual Labs Online
There would have always been lots of sources for virtual lab access to Cisco environments online, but only in 2012 did Cisco itself would be dipping a toe into these waters by launching of the Cisco Virtual Labs.
8. Cisco Certification Training
As is so often the case for training on certifications of the vendor-specific, you would have an important choice in order to make when you would be seeking out training on Cisco certifications to go through an authorized Cisco training partner that would be taught elements of the Cisco official training curriculum, or in order to go outside the Cisco channel so as to find a solid, reputable third-party training provider.
CCIE R&S Certification would be achieved without proper training module, for which I would recommend you to join the SPOTO, as it provides you with the training along with the passing guarantee.
The Cisco Certified Network Associate Routing and Switching Certification otherwise known as CCNA R&S Certification is considered to be a top IT certification and is also considered to be one of the most respected certifications in the world. An associate-level certification for IT networking, it would be helping the candidates, to boost their professional career by having better jobs as well as higher pay. The CCNA R&S certification is going to prove, that an individual is capable of configuring, operating, as well as troubleshoot routed and switched networks. To achieve this certification is quite hard, but if you wish to do it in an easy way, your best bet would be to enroll yourself into the training provided by a well reputed and reliable firm like the SPOTO.
Obtaining the CCNA R&S Certification Faster would require:
Obtaining Practical Experience:
You are going to need both theoretical as well as practical knowledge to clear the CCNA Routing and Switching exam. As you prepare for the exam, you would be able to utilize the theoretical information in real-world networking and troubleshooting issues.
Obtaining the Proper Study Materials
CCNA Routing and Switching preparation are going to include the gathering of the right study materials. The best materials for studying for the CCNA Routing and Switching exam would be the latest editions of Cisco’s own books: Cisco CCENT/CCNA ICND 1 as well as CCNA Routing and Switching ICND2. 31 Days Before series would be also recommended to go through which would be available through the Cisco Press. You need to make sure that it covers the practice questions and lab exercises. But before you actually start with the aforementioned books, you are required to go through the easy to acquire training courses, which are being offered at the SPOTO, for easing up the candidate’s study path.
Scheduling Practice Tests
The candidates are then required to schedule practice tests well in advance of their scheduled exam date. You are also needed to set a deadline for yourself and should check out what you have learned in between that time. You would be able to discover the areas where you are most needed to improve.
Refreshing Your Knowledge before the Commencement of Exam
The candidates are recommended to read and reread the Cisco Press books again and again before they schedule their exam date. This is going to help you out to refresh your memory, as well as help you to identify anything that you might have skipped over the first time. The last couple of weeks before the commencement of the exams the candidates should be completely devoted to solving questions. They should try to find new questions by going through the internet forums as well as other platforms of the online mock test as you might be able to find. The candidates are required to point out when you would be having effectively grasped the concepts of networking that would be on your CCNA Routing and Switching certification
The CCNA Routing and Switching Certification wouldn’t be just opening the doors to networking success, but you would be also enabling yourself to market yourself as a networking expert along with global recognition. The CCNA Routing and Switching certification would also be proving that you are considered to be more knowledgeable than non-certified professionals. Thus it is totally worth it to acquire this certification and for that, you would be required to go through lots and lots of study process. But if you wish to ease up your certification path, you must gain the training courses, provided by the SPOTO, they are considered to be the best in the IT Sector.
This debate between Layer 2 VPN services based on MPLS and Layer 3 MPLS VPNs are widely asked and is considered to be largely theoretical; Layer 2 VPN service is not widely available yet. If you wish to have more knowledge regarding the same, join the courses offered by the SPOTO, and have relevant knowledge for your studies.
But the two are different enough for potential customers of one or both of the services so as to consider now how they might fit into current networks. At the recent MPLScon 2006 conference, businesses that would be utilizing MPLS services talked about Layer 2 vs. Layer 3 services in some detail, and it would be quite apparent that neither one would be defeating the other.
Actually, the IP network tends to work over the MPLS. The idea of MPLS is that a series of labels could be applied to a given packet or frame that could consequently be used to switch it through a network. In the case of an L3VPN, it would be meaning that rather than the traditional mechanism of looking at the destination IP address, routing devices have looked at one or more previously applied labels to make the decisions of forwarding.
The key point in the above scenario is that the actual contents of the packet aren't actually considered. Once a given packet is being labeled the intervening devices would be simply forwarding it on the basis of whatever LSP has been signaling. In the case of an L3VPN, the packet is considered to be a fully formed IP packet. In the case of an L2VPN a frame from a particular interface would have been added a label and is forwarded. This might be considered being a full Ethernet frame i.e. with or without an 802.1q header, an HDLC frame from a serial link, one or more cells from an ATM PVC, etc.
One of the major differences between L2 and L3 VPN is the mechanism utilized to signal and set up the overlay network. L3VPN (RFC2547bis) would be extending the BGP protocol so as to allow PE's for signaling which routes are available within which VPN's. There would be more possible ways to put together a layer 2 network like, straight point-to-point links, multipoint, translational, etc, and there are also more mechanisms in use in the industry which could be utilized to signal these various topologies.
Layer 3 MPLS VPNs would be exemplify by fully meshed architectures that enable, for example, multicast conferencing in support of projects which would involve a dispersed workgroup. Layer 2 MPLS technology is considered to be limited in this area because it doesn’t scale quite well as Layer 3.
Some businesses like the Layer 3 options that would be obtainable now because the service provider takes over all the WAN routing, whereas, with a Layer 2 WAN, like the MPLS-based VPLS (virtual private LAN services), businesses would have to handle the routing on their own, customers noted.
Outsurcing of routing tables would also be seen as a weakness of Layer 3 VPN services because many corporations do not want to relinquish control or even share their routing schemes with any other corporation, not even their service provider. They prefer Layer 2 network services, like the frame relay or ATM, that are simpler in architecture as well as allow customers to retain control of their own routing tables.
Thus, you would have gone through the various differences between the L2VPN and L3VPN. If you have more queries regarding it, or regarding any IT Certification, you could visit the SPOTO and gain the knowledge through their expert professionals.

Fast Convergence and the Fast Reroute Network reliability is considered to be an important design aspect for deployability of time and loss sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network re-converges on the new topology. Before we move on to discuss them further, if you wish to have more information, you could obtain by joining the SPOTO.
Fast reaction is very much essential for the failed element for some applications. There are two approaches for the fast reaction in case of failure: Fast convergence and fast reroute. Although people use these terms interchangeably, they are not the same thing.
When a local failure occur four steps are necessary to be taken for the convergence. These steps should be completed before traffic continues on the backup/alternate link.
1. Failure detection (Protocol Hello Timers, Carrier Delay and Debounce Timers, BFD and so on)
2. Failure propagation (LSA and LSP Throttling timers)
3. New information process (Alternate/Backup path calculation) (SPF Wait and Run times)
4. Update new route into RIB/FIB (After this step, traffic can continue to flow through the backup link)
For fast convergence, these steps are tuned. Tuning the timers mean generally lowering them as most vendors use higher timers to be on the safe side. Because as you will see later in this post, lowering these timers can create stability issue in the network.
When you tune the timers for failure detection, propagation, and the new path calculation, it is called fast convergence. Because traffic could be continued towards alternate link faster than regular convergence since you use lower timers. (Instead of 30seconds hello timer, you can use 1 second hello, or instead of 5 seconds SPF wait time, you can make it 10 ms and so on.)
Although the RIB/FIB update is hardware dependent, the network operator can configure all the other steps.
One thing the candidates should need to be kept in mind always; Fast convergence and fast reroute can affect network stability. If you configure the timers very low, you might see false-positives.
Unlike fast convergence, for the fast reroute, the backup path is pre-computed and pre-programmed into the router RIB/FIB. This increases the memory utilization on the devices.
There are many Fast Reroute mechanisms available today. Most popular ones are; Loop-Free Alternate (LFA), Remote Loop-Free Alternate (rLFA), MPLS Traffic Engineering Fast Reroute and Segment Routing Fast Reroute. The main difference between MPLS Traffic Engineering Fast Reroute and the IP Fast Reroute mechanisms are the coverage.
MPLS TE FRR can protect any traffic in any topology. IP FRR mechanisms are needed for the physical topology of the networks to be highly connected.
Ring and square topologies are hard for the IP FRR topologies but not a problem for MPLS TE FRR at all. In other words, finding a backup path is not always possible with IP FRR mechanisms if the physical topology is ring or square. Best physical topologies from this aspect are full mesh.
If MPLS wouldn’t be enabled on the network, adding MPLS and RSVP-TE for just MPLS TE FRR functionality is considered as complicated. In that case network, designers may want to evaluate their existing physical structure and try to alternate/backup path by adding or removing some circuit in the network. IGP metric tuning also helps the router to find alternate loop-free paths.
Thus If you wish to have more related knowledge, join SPOTO and help yourself out with their expert training courses, for various IT Sectors. SPOTO is the one stop destination for a networking candidate.
The CCIE Security is often considered as the Ph.D. of Cisco certifications. We would be discussing its value to your career and the demands which would be required to achieve becoming a Cisco Certified Internetwork Expert Security in a previous blog post. It would be an amazing accomplishment and once you have done it, there comes an inevitable question, and that is what do you do next?
Here are a few things to do for the progression of your career, once you’ve accomplished CCIE greatness.
Now that you’re rested up, the time has come to face the cold hard truth of Cisco certification. Without recertifying, the certification would expire, and all your time and effort which would be down the tube. Don’t get afraid though, Cisco is very clear about what would be required for their recertification. It would be benefitting you to start planning now, so the two-year deadline doesn’t sneak up upon you.
The first option for recertifying would be to earn credits through the Cisco Continuing Education Program. Participants would have to take courses to earn credits, and 100 credits within two years would be able to re-certify you. The course offerings would be included a variety of breakouts, technical seminars, as well as instructor-led labs that would be designed to keep your skills sharp and diversify your skill set.
Recertifying with Cisco Certs:
Another option, through which you could recertify your CCIE Security Exam, is to take another CCIE. Like the CCNA and CCNP, the CCIE would also have separate certifications for different concentrations. You may have your CCIE in Routing and Switching or in Voice, or Data Center next. Each CCIE Certification would be able to provide a unique layer of specialization to your resume, which you have already impressive. But the question again lies, and that is which certification to choose.
CCIE Data Center After CCIE Security:
Mostly the candidates who have just completed their CCIE Security Exam goes for the CCIE Data Center Certification. CCIE Data Center Certification would always have been top-notch in terms of minimal power consumption, efficient processing capabilities as well as ease of management through means of its software which would be based Data Center managers. Gaining a CCIE Data Center Certification, wouldn’t just consider the best way to recertify to the CCIE Security certification, but it would also help you out in gaining the jobs, which you were unable to gain it with the CCIE Security Certification. Not to mention that two CCIEs would be able to earn you more salary, reputation, job opportunities, than that of one CCIE Certification. Also, once you have cleared the CCIE Security Certification, it would definitely help you out in your CCIE Data Center Certification.
CISSP After CCIE Security Certification:
Here’s the first thing that you should know, and it is quite important. The CISSP certification is unachievable if you’re just beginning out in a security role. Sure, you would be able to take and clear the exam. But you won’t be able to earn the certification until you have achieved five years of paid work experience. There would be ways to shorten that time by a year.
On the bright side, there are great reasons for earning the CISSP if you don’t have earned the five years of paid work experience. You could still become an (ISC)² Associate by just clearing the CISSP certification exam. CISSP Associates gain exclusive access to (ISC)² career resources as well as networking groups. They’re also considered to be more desirable to employers, especially federal ones.
Also, both of these certifications are related to Security. Having a CCIE Security would help you out in achieving the CISSP Certification, as both of them are similar to some extent.
Now, whichever way you choose, if you have faced difficulty in achieving the CCIE Security Certification, you don’t have to face it again. Join the courses offered by the SPOTO and obtain the next course, whichever it would be, i.e. CCIE Security and CISSP.
Cisco Systems Inc specializes in networking as well as communications products and services. The company is probably known to be the best for its business routing and switching products, which direct voice, video, and data traffic across networks around the world.

Cisco's expert-level certifications
Cisco's expert-level credentials would be embracing two primary certifications: the coveted Cisco Certified Internetwork Expert or the CCIE Certification and the Cisco Certified Design Expert or the CCDE Certification. Neither certification would be imposing prerequisites, but the candidate would be needed to clear a written exam and a rigorous practical exam so as to earn either of these credentials.
Pros of CCIE:
Once you have obtained CCIE certification with a specific vendor or manufacturer, then you would have to join a unique group of certified skilled professionals as well as get ample of new job opportunities after the course completion.
Cisco CCIE professionals are the highest-paid IT professionals across the globe. This field is going to offer quite pleasing salary packages for all the CCIEs or other networking professionals as compared to other technical fields.
There would be ample growth opportunities if you’ll opt for Cisco CCIE security v5 certification. The career opportunities are vast. You’ll be experienced more growth opportunities because the IT industry needs CCIEs more. If a candidate has more than 5 years of experience in the relative field, then the salary package offered would be more than $28,619 USD per annum, which would be a great salary amount.
Cons of CCIE:
Understandably, if you want to earn a certificate, you must be ready to invest. However, the investment should not be something that will cripple your finances.
