authentication-key: Authentication key. When you specify authentication-type as
simple, the authentication key can contain up to eight characters. When you specify
authentication-type as md5, the authentication key can be a string comprising up to
eight characters in plain text or a 24-character encrypted string.
Description
Use the vrrp authentication-mode command to specify the authentication type and
the authentication key for a VRRP backup group.
Use the undo vrrp authentication-mode command to clear the configured
authentication type and authentication key.
If the simple or md5 authentication is configured, the authentication key is required.
This command sets the authentication type and authentication key for all the VRRP
backup groups on an interface. As defined in the protocol, all the backup groups on an
interface share the same authentication type and authentication key. And all the
members joining the same backup group also share the same authentication type and
authentication key.
Note that the authentication key is case-sensitive.
