Configuring VRRP Authentication

A version 2 VRRP VRID can be configured for a simple clear text or encrypted MD5 authentication password. For MD5 authentication, 128-bit encryption is used unless the hmac-96 option is specified, in which case 96-bit encryption is used.

Use the vrrp authentication command in interface configuration command mode, specifying the authentication type, a password, and in the case of MD5 optionally specifying 96-bit encryption.
