ip rip authentication key
■
Use to specify either the simple password for text authentication or the
encryption/decryption key for MD5 authentication. The key is a string of up to
16 alphanumeric characters and can be mixed uppercase and lowercase.
■
You can specify whether the key is entered in unencrypted or encrypted format.
If you do not specify which, the string is assumed to be unencrypted.
■
Example
host1(config-if)# ip rip authentication key ke6G72mV
■
Use the no version to clear all authentication keys.
■
See ip rip authentication key
ip rip authentication mode
■
Use to specify the authentication mode.
■
Specify text to send a simple text password to neighbors. If a neighbor does not
have the same password, requests and updates from this router are rejected.
■
Specify md5 keyID to send an MD5 hash to neighbors. Neighbors must share
the MD5 key to decrypt the message and encrypt the response.
■
Example
host1(config-if)# ip rip authentication mode text
