Guide to Routing Information Protocol (RIP)
What is RIP?
Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination.
Why is it Important?
RIP is important because it helps in decision-making about the best path for data packets to reach a desired destination. This makes it crucial for proper network trafficking and organization.
How does it Work?
RIP uses Bellman-Ford's distance-vector algorithm to decide the optimal path for data transmission. The administrative distance value for RIP is 120. The path which has the least total metric will be selected as the best path.
It works on the application layer of the OSI model (specifically UDP port number 520).

Routing Information Protocol (RIP) practice test
Routing Information Protocol (RIP) is a distance-vector routing protocol used to exchange routing information among routers within the same network. RIP uses hop count, which is the number of routers a packet has to pass through to reach its destination, as the metric to determine the best path for data transmission. It periodically broadcasts its routing table to other routers within the network in order to maintain an updated knowledge of the network topology. However, RIP has limitations, such as a maximum hop count of 15, which hinders its use in larger networks. There are two versions of RIP: RIPv1, which doesn't support CIDR and uses classful addressing, and RIPv2, which supports CIDR and includes features like authentication and multicasting.
