Purpose of Dynamic Routing Protocols

Purpose of Dynamic Routing Protocols

A routing protocol is a set of processes, algorithms, and messages that are used to exchange
routing information and populate the routing table with the routing protocol’s choice of best
paths. The purpose of a routing protocol includes■ Discovering remote networks■ Maintaining up-to-date routing information■ Choosing the best path to destination networks■ Having the ability to find a new best path if the current path is no longer available
The components of a routing protocol are as follows:■ Data structures: Some routing protocols use tables or databases for their operations.
This information is kept in RAM.

■ Algorithm: An algorithm is a finite list of steps used in accomplishing a task. Routing protocols use algorithms for processing routing information and for best-path determination.■ Routing protocol messages: Routing protocols use various types of messages to discover neighboring routers, exchange routing information, and do other tasks to learn and
maintain accurate information about the network.  Click Here
