Interface VRRP Commands
vrrp
Syntax vrrp virtual-router-id [owner]
no vrrp virtual-router-id
Context config>service>vprn>interface
Description This command creates or edits a Virtual Router ID (VRID) on the service IP interface. A VRID is
internally represented in conjunction with the IP interface name. This allows the VRID to be used on
multiple IP interfaces while representing different virtual router instances.
Two VRRP nodes can be defined on an IP interface. One, both, or none may be defined as owner. The
nodal context of vrrp virtual-router-id is used to define the configuration parameters for the VRID.
The no form of this command removes the specified VRID from the IP interface. This terminates
VRRP participation for the virtual router and deletes all references to the VRID. The VRID does not
need to be shutdown in order to remove the virtual router instance.
Default No default
Parameters virtual-router-id — The virtual-router-id parameter specifies a new virtual router ID or one that can
be modified on the IP interface.
Values 1 — 255
authentication-key
Syntax authentication-key [authentication-key | hash-key] [hash | hash2]
no authentication-key
Context config>service>vprn>if>vrrp
config>service>vprn>if>vrrp
Description The authentication-key command, within the vrrp virtual-router-id context, is used to assign a
simple text password authentication key to generate master VRRP advertisement messages and
validate received VRRP advertisement messages.
The authentication-key command is one of the few commands not affected by the presence of the
owner keyword. If simple text password authentication is not required, this command is not required.
If the command is re-executed with a different password key defined, the new key will be used
immediately. If a no authentication-key command is executed, the password authentication key is
restored to the default value. The authentication-key command may be executed at any time, altering
the simple text password used when authentication-type password authentication method is used by
the virtual router instance. The authentication-type password command does not need to be
executed prior to defining the authentication-key command.
To change the current in-use password key on multiple virtual router instances:
• Identify the current master
