Create 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 INTERFACE mode (Figure 38-2). To delete a
VRRP group, use the
no vrrp-group vrid command in INTERFACE mode.
Figure 38-2. vrrp-group Command Example
Task Command Syntax Command Mode
Create a virtual router for that interface
with a VRID.
VRID Range: 1 to 255
vrrp-group vrid INTERFACE
Note: The interface must already have a Primary IP Address defined and
be enabled.
