10.2.7 Application of authentication

Apply the authentication functionality to RIP-2 packets transmitted through a specific interface.

Points to note

The example below shows how to, using the ip rip authentication key command, set the key identifier, authentication method, and authentication key for RIP-2 packets. Use the same authentication key for all routers in the same network.

Command examples

1. (config)# interface vlan 1

   (config-if)# ip rip authentication key 1 md5 a1w@9a

   (config-if)# ip rip version 2

   Applies RIP-2 authentication to the interface vlan 1.

   Sets 1 as the key identifier, cryptographic authentication (Keyed-MD5) as the authentication method, and alw@9a as the authentication key.
