Introduction to RIPv2

RIPv2 (Routing Information Protocol version 2) is a distance-vector routing protocol that is used to exchange routing information among routers. It is an improvement over RIPv1, with support for subnet masks, classless inter-domain routing (CIDR), and multicast updates.

Theory

RIPv2 uses the following key concepts:

• Distance-vector algorithm: RIPv2 uses a distance-vector algorithm to calculate the best path to a destination network. Each router maintains a routing table that lists the best path to each destination network.
• Hop count: RIPv2 uses hop count as the metric to determine the best path. The hop count is the number of routers that a packet must pass through to reach the destination network.
• Split horizon: RIPv2 uses split horizon to prevent routing loops. Split horizon means that a router will not advertise a route back to the router from which it learned the route.

Configuration RIPv1 in R1

R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
R1(config-router)#network 192.168.1.0
R1(config-router)#network 192.168.10.0
R1(config-router)#end

R1 Verification

R1#show ip route
R1#show ip protocols
R1#show ip rip database

Configuration RIPv2 in R2

R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 192.168.1.0
R2(config-router)#network 192.168.10.0
R2(config-router)#end

R2 Verification

R2#show ip route
R2#show ip protocols
R2#show ip rip database

Configuration RIPv2 in R3

R3(config)#router rip
R3(config-router)#version 2
R3(config-router)#no auto-summary
R3(config-router)#network 192.168.1.0
R3(config-router)#network 192.168.10.0
R3(config-router)#end

R3 Verification

R3#show ip route
R3#show ip protocols
R3#show ip rip database
