Here is a basic overview of the configuration of RIP on a Cisco router:

Router(config)#router rip

Router(config-router)#network 192.168.1.0

Router(config-router)#network 192.168.2.0

Router(config-router)#network 192.168.3.0

Router(config-router)#network 192.168.4.0

Router(config-router)#network 192.168.5.0

The 192.168.x.0 address can be changed to whatever address you would like to be broadcast over RIP. There are also other settings that can be configured.

If you use RIPv2 you can also have the following configuration:

Router(config)#router rip

Router(config-router)#version 2

Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.2.0
Router(config-router)#network 192.168.3.0
Router(config-router)#network 192.168.4.0
Router(config-router)#network 192.168.5.0

Router(config-router)#exit

Router(config)#exit
