Configuring IP Unicast Routing
Configuring Basic RIP Parameters
To configure RIP, you enable RIP routing for a network and optionally configure other parameters. RIP
configuration commands are ignored on the switch until you configure the network number.
Beginning in privileged EXEC mode, follow these steps to enable and configure RIP:
Command
Step 1
configure terminal
Step 2
ip routing
Step 3
router rip
Step 4
network network number
Step 5
neighbor ip-address
Step 6
offset list [access-list number | name]
{in | out} offset [type number]
Step 7
timers basic update invalid holddown
flush
Step 8
version {1 | 2}
Step 9
no auto summary

Purpose
Enter global configuration mode.
Enable IP routing. (Required only if IP routing is disabled.)
Enable a RIP routing process, and enter router configuration mode.
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.
You must configure a network number for RIP commands to take
Note
effect.
(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.
(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.
(Optional) Adjust routing protocol timers. Valid ranges for all timers are
0 to 4294967295 seconds.
•
update—The time between sending routing updates. The default is
30 seconds.
•
invalid—The timer after which a route is declared invalid. The
default is 180 seconds.
•
holddown—The time before a route is removed from the routing
table. The default is 180 seconds.
•
flush—The amount of time for which routing updates are postponed.
The default is 240 seconds.
(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 commands ip rip {send | receive} version
1 | 2 | 1 2} to control what versions are used for sending and receiving on
interfaces.
(Optional) Disable automatic summarization. By default, the switch
summarizes subprefixes when crossing classful network boundaries.
Disable summarization (RIP Version 2 only) to advertise subnet and host
routing information to classful network boundaries.
