Description
Use the

and its parameters.
Use the
undo rip authentication-mode
command to cancel RIP-2 authentication
mode.
RIP-1 does not authenticate packets. Generally RIP authenticates packets in two
modes: plaintext authentication and MD5 ciphertext authentication. There are two
packet formats in the MD5 ciphertext authentication: one format conforms to RFC
2453 and the other format is described in RFC 2082. Routers support both formats.
You can select any format as required.
