ip rip authentication key-chain name-of-chain
no ip rip authentication key-chain [name-of-chain]


Syntax Description:

name-of-chain Enables authentication and specifies the group of keys that are valid.


Command Description:

To enable authentication for Routing Information Protocol (RIP) Version 2 packets and to specify the set of keys that can be used on an interface, use the ip rip authentication key-chain command in interface configuration mode. To prevent authentication, use the no form of this command.

If no key chain is configured with the key-chain command, no authentication is performed on the interface (not even the default authentication).

By default, no authentication is provided for RIP packets.


The following example configures the interface to accept and send any key belonging to the key chain named trees:

Router(config-if)#ip rip authentication key-chain trees
