Context

Description
This command sets the simple text authentication key used to generate master VRRP advertisement
messages and validates VRRP advertisements.
If simple text password authentication is not required, the authentication-key command is not
required.
The command is configurable in both non-owner and owner vrrp nodal contexts.
The key parameter identifies the simple text password to be used when VRRP Authentication Type 1
is enabled on the virtual router instance. Type 1 uses an eight octet long string that is inserted into all
transmitted VRRP advertisement messages and is compared against all received VRRP advertisement
messages. The authentication data fields are used to transmit the key.
The key string is case sensitive and is left justified in the VRRP advertisement message authentication
data fields. The first field contains the first four characters with the first octet (starting with IETF RFC
bit position 0) containing the first character. The second field similarly holds the fifth through eighth
characters. Any unspecified portion of the authentication data field is padded with a 0 value in the
corresponding octet.
