| 12.3.3 | Enabling RIP on an IP-addressed network
In the example, the descriptions for the commands are as follows: router rip -- selects RIP as the routing protocol network 1.0.0.0 -- specifies a directly connected network network 2.0.0.0 -- specifies a directly connected network The Cisco A router interfaces that are connected to networks 1.0.0.0 and 2.0.0.0 send and receive RIP updates. These routing updates allow the router to learn the network topology.
