Description
■ Use the vrrp authentication-mode command to configure the
authentication type and key of a specified VRRP virtual router.
■ Use the undo vrrp authentication-mode command to clear the
authentication type and key of a specified VRRP virtual router.
If the simple or md5 authentication is configured, it is required to set the
authentication key.
This command is used to configure the authentication type and key for all the
VRRP virtual routers on an interface. As defined in the protocol, all the virtual
routers on an interface use the same authentication type and key. In addition, all
the members joining the same virtual router also use the same authentication type
and key.
When the authentication type and key are set, the upper/lower cases are not
necessary to be matched.
Example
