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.
(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.
(Optional) Disable validation of the source IP address of incoming RIP
routing updates. By default, the switch validates the source IP address of
incoming RIP routing updates and discards the update if the source
address is not valid. Under normal circumstances, disabling this feature
is not recommended. However, if you have a router that is off-network
and you want to receive its updates, you can use this command.
(Optional) Add interpacket delay for RIP updates sent.
By default, packets in a multiple-packet RIP update have no delay added
between packets. If you are sending packets to a lower-speed device, you
can add an interpacket delay in the range of 8 to 50 milliseconds.
Return to privileged EXEC mode.
