VRRP Configuration
By default, VRRP is not configured.
The following list specifies the configuration tasks for VRRP:
• Create a Virtual Router on page 1131 (mandatory)
• Assign Virtual IP addresses on page 1132 (mandatory)
• Set VRRP Group (Virtual Router) Priority on page 1135 (optional)
• Configure VRRP Authentication on page 1136 (optional)
• Disable Preempt on page 1137 (optional)
• Change the Advertisement interval on page 1138 (optional)
• Track an Interface or Object on page 1139 (optional)
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 on a physical or VLAN interface. In FTOS, a VRRP
Group is identified by the Virtual Router Identifier (VRID).
Starting in release 8.4.1.0, you can configure a VRRP group on an interface that belongs to a non-default
VRF instance.
Prerequisite: The interface on which you create the virtual interface must be enabled and configured with
a primary IP address.
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.

Task Command Syntax Command Mode
Assign an interface (physical or
VLAN) to an IPv4 or IPv6 VRRP
group.
