Here in, we would give you an overview of dynamic routing protocols. We would be defining them and learning about how they are different from static routes. We would be also discussing their advantages over static routes, learning the different categories of dynamic routing protocols and classless as well as classful nature. We would be also talking about the administrative distance and the metric. The administrative overhead that is going to be needed to make communication between all these devices would be considerable. All the static routes would be needed to be configured.
Wouldn’t it be considered much easier, for the network administrator in order to just “Teach” the routers about how to get from one point to another? The solution to this problem would be the dynamic routing protocols. Dynamic routing protocols would be considered as a solution that would be utilized in large networks in order to reduce the complexity in a configuration that would be occasioned by having to configure static routes. In most networks, you would see a mixture of both dynamic as well as static routes.
femme grosse rencontre Definition of Dynamic Routing Protocols:
Routing protocols which would be used to enable the routers exchange routing information, they would be also allowing routers to learn about remotely connected networks dynamically. This information is then going to be added to their routing tables as a basis for forwarding the packets. To learn more about it, join the SPOTO, and gain their expertise courses.
Go Here Classification
Dynamic routing protocols are going to be classified in several ways. Some of them are mentioned below:
- Interior and exterior gateway routing protocols,
- Distance vector, path vector and link state routing protocols,
- Classful and classless.
Although you might not be examined on the information which is mentioned above directly, both exams would have questions that would require knowledge of this information.
Operation of routing protocols
Now that we have an overview of routing protocols, we might be needed to understand how they work. Routing protocols would be consisting of processes, messages as well as algorithms that are used by routers to learn about remotely connected networks from routers that would have been configured with the same routing protocols, the routes that have been learned are going to be added to the routing table and used as a basis for forwarding packets.
Routing protocols are going to be functioned by:
- Discovering remote networks
- Maintaining current routing information
- Path determination
The routing protocol would be made up of these components.
- Data structures:
This would be considered as information about remote networks. It would be usually stored in the RAM as well as it might be comprised of tables like the neighbor tables as well as topology tables.
This is considered as the sequential list of steps that the routing would take when determining the best path to a particular network.
- Routing protocol messages:
These are messages that would be utilized for maintaining updated routing information. As for Examples; hello messages, update messages among others.
Advantages and disadvantages
Now that we have known about the dynamic routing protocols, we would be needed to know the advantages and disadvantages of using dynamic routing protocols. We would also need to compare them to static routes.
- Exchanging of routing information when there is a topology change is dynamic.
- Less administrative overhead so as compared to static routes which would have to be manually configured
- Less error is prone than static routing.
- Scalability, since there would be less administrative overhead than the static routes.
- It would be requiring more expertise by the administrator, they aren’t as simple to configure as compared to static routes.
- They would be utilizing more of the router’s resources; like the CPU and RAM.
So, if you are willing to have more details regarding the same join the relevant courses which are being offered by the SPOTO.
