Creating a Virtual Router
To enable VRRP, you must create a Virtual Router. In FTOS, a VRRP Group is identified by the Virtual
Router Identifier (VRID).
To enable a Virtual Router, use the following command in the INTERFACE mode. To delete a VRRP
group, use the
no vrrp-group vrid command in the INTERFACE mode.
Figure 55-2. Command Example: vrrp-group
Figure 55-3. Command Example Display: show config for the Interface
Assigning Virtual IP addresses
Virtual routers contain virtual IP addresses configured for that VRRP Group (VRID). A VRRP group does
not transmit VRRP packets until you assign the Virtual IP address to the VRRP group.
Task Command Syntax Command Mode
Create a virtual router for that interface
with a VRID.

Note: The interface must already have a Primary IP Address defined, and
be enabled.
