| 12.3.2 | Using router rip and network commands to enable RIP
The router rip command selects RIP as the routing protocol. The network command assigns a NIC-based network address to which a router will be directly connected. The routing process associates interfaces with the network addresses and begins using RIP on the specified networks. Note: In RIP all subnet masks must be the same. RIP does not share subnetting information in routing updates.
