Virtual Router Redundancy Protocol (VRRP) | 1047
• Disable Preempt (optional)
• Change the Advertisement interval (optional)
• Track an Interface or Object (optional)
• VRRP initialization delay
For a complete listing of all commands related to VRRP, refer to FTOS Command Line Interface.
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 the INTERFACE mode. To delete a VRRP
group, use the
no vrrp-group vrid command in the INTERFACE mode.
Figure 54-2. Command Example: vrrp-group
Figure 54-3. Command Example Display: show config for the Interface
Assign 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.
E-Series supports an unlimited total number of VRRP Groups on the router while supporting up to 255
VRRP groups on a single interface (Table 54-1).

Create a virtual router for that interface
with a VRID.

be enabled.
