Routing Information Protocol (RIP)April 24, 2025 Routing Information Protocol (RIP) RIP is a routing protocol that uses hop count as a routing metric to find the best path between the source and the destination network. the maximum hop count allowed is 15 it is mostly used in small to medium sized network What is Hop count? Hop count is the numbers of router in the path from the source to the destination network. The path with the lowest hop count is considered as the best route RIP prevents routing loops by limiting the hops allowed in a path RIP allows max is 15 hops when there is 16 hops the network is considered as unreachable How does RIP works? RIP uses distance vector routing to find the routing information. RIP maintains a routing table where the distance to each destination is mentioned. RIP shares the routing tables to its neighbor in an interval of 30 seconds through broadcasting. Each router update its routing table accordingly once the routing information has been received. RIPv1 does not support authentication of the updated message only supports classful routing RIPv2 : supports authentication of the updated message supports classless routing note: To check the route in cisco router: - show ip route To check the protocols used in router: - show ip protocols note: To check the route in cisco router: - show ip route To check the protocols used in router: - show ip protocols RIP configuration: Routing protocol configuration: #router rip #network 10.10.10.0 #network 172.16.10.0 #version 2 #no auto-summary reference “https://www.geeksforgeeks.org/routing-information-protocol-rip/”
