Chapter22 Configuring IP Unicast Routing
Configuring RIP
For protocol-independent features that also apply to RIP, see the “Configuring Protocol-Independent
Features” section on page 22-53.
To configure RIP, you enable RIP routing for a network and optionally configure other parameter s.
Beginning in privileged EXEC mode, follow these steps to enable and configure RIP:
Validate-update-source Enabled.
Version Receives RIP version 1 and version 2 packets;
sends version 1 packets.
Table22-5 Default RIP Configuration (continued)
Feature Default Setting
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 ip routing Enable IP routing. (Required only if IP routing is disabled.)
Step3 router rip Enable a RIP routing process, and enter router configuration mode.
Step4 network network number Associate a network with a RIP routing process. You can specify multiple
network commands. RIP routing updates are sent and received through
interfaces only on these networks.
Step5 neighbor ip-address (Optional) Define a neighboring router with which to exchange routing
information. This step allows routing updates from RIP (normally a
broadcast protocol) to reach nonbroadcast networks.
Step6 offset list [access-list number | name]
{in | out} offset [type number](Optional) Apply an offset list to routing metrics to increase incoming
and outgoing metrics to routes learned through RIP. You can limit the
offset list with an access list or an interface.
Step7 timers basic update invalid holddown
flush (Optional) Adjust routing protocol timers. Valid ranges for all timers are
0 to 4294967295 seconds.
•update—The time (in seconds) between sending of routing updates.
The default is 30 seconds.
•invalid—The timer interval (in seconds) after which a route is
declared invalid. The default is 180 seconds.
•holddown—The time (in seconds) that must pass before a rou te is
removed from the routing table. The default is 180 seconds.
•flush—The amount of time (in seconds) for which routing updates
are postponed. The default is 240 seconds.
Step8 version {1 | 2} (Optional) Configure the switch to receive and send only RIP Version 1
or RIP version 2 packets. By default, the switch receives Version 1 and 2
but sends only Version 1.
You can also use the interface comm ands ip rip {send | receive} version
1 | 2 | 1 2} to control what versions are used for sending and receiving on
interfaces.
Step9 no auto summary (Optional) Disable automatic summarization. By default, the switch
summarizes subprefixes when crossing classful network boundaries.
Disable summarization (RIP version 2 only ) t o ad vertise subnet and host
routing information to classful network boundaries.
