AI2524 RIP TCP/
IP Configuration Routing Information Protocol (RIP) uses broadcast User Datagram
Protocol (UDP) data packets to exchange routing information.
The Cisco IOS software sends routing information updates (advertise-
ments) every 30 seconds. If a router does not receive an update from
another router for 180 seconds or more, it marks the routes served by
the nonupdating router as being unusable. If there is still no update
after 240 seconds, the router removes all routing table entries for the
nonupdating router.
RIP sends updates to the interfaces in the specified networks. If an in-
terface's network is not specified, it will not be advertised in any RIP
update.
RIP Configuration Task List
To configure RIP, complete the tasks outlined in the nest sections. You
must enable RIP. The remaining tasks are optional.
z Enable RIP
z Allow Point-to-Point Updates for RI
z Specify a RIP Version
z Enable RIP Authentication
z Disable Route Summarization
z Run IGRP and RIP Concurrently
z Disable the Validation of Source IP Addresses
Enable RIP
To enable RIP, perform these tasks, starting in global configuration
mode:
1. Enable a RIP routing process, which places you in router configu-
ration mode.

2. Associate a network with a RIP routing process.

Allow Point-to-Point Updates for RIP
RIP is normally a broadcast protocol. Therefore, for RIP routing up-
dates to reach point-to-point or nonbroadcast networks, you must con-
figure the Cisco IOS software to permit this exchange of routing
