After enabling RIP, you need to specify the network segment in which RIP runs. RIP runs only on the interfaces on the specified network segment. RIP does not receive, send, or forward routes on the interfaces that do not reside on the specified network segment.

rip [ process-id ]
network network-address
network-address specifies the address of a natural network segment.
An interface can be associated with only one RIP process.
If any network segment in which an interface configured with multiple sub-interface IP addresses resides is associated with a RIP process, the interface cannot be associated with any other RIP processes.
