To turn off the RIP routing process, use the no router rip global configuration command.
To display the parameters and current state of the active routing protocol process, use the show ip
protocols privileged EXEC command. Use the show ip rip database privileged EXEC command to
display summary address entries in the RIP database.

Configuring RIP Authentication

RIP Version 1 does not support authentication. If you are sending and receiving RIP Version 2 packets,
you can enable RIP authentication on an interface. The key chain specifies \the set of keys that can be
used on the interface. If a key chain is not configured, no authentication is performed, not even the
default. Therefore, you must also perform the tasks in the
OL-25303-03
Purpose
(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.
Verify your entries.
(Optional) Save your entries in the configuration file.
