Specify RIP Version
Configure a router to receive and send specific versions of packets on an interface. In this example, router R2 is configured to receive and send RIP version 1 and version 2 information on both eth1 and eth2 interfaces.

#configure terminal | Enter configure mode |
(config)#router rip | Enable the RIP routing process |
(config-router)#exit | Exit router mode |
(config)#interface eth1 | Enter interface mode |
(config-if)#ip rip send version 1 2 | Send RIP version 1 and version 2 packets out this interface |
(config-if)#ip rip receive version 1 2 | Receive RIP version 1 and version 2 packets from this interface |
(config-if)#exit | Exit interface mode |
(config)#commit | Commit the candidate configuration to the running configuration |
(config)#interface eth2 | Enter interface mode |
(config-if)#ip rip send version 1 2 | Send RIP version 1 and version 2 packets out this interface |
(config-if)#ip rip receive version 1 2 | Receive RIP version 1 and version 2 packets from this interface |
(config-if)#exit | Exit router mode and return to configure mode. |
(config)#commit | Commit the candidate configuration to the running configuration |
