Virtual Router Redundancy Protocol (VRRP) | 1131VRRP ConfigurationBy 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 RouterTo enable VRRP, you must create a Virtual Router on a physical or VLAN interface. In FTOS, a VRRPGroup 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-defaultVRF instance.Prerequisite: The interface on which you create the virtual interface must be enabled and configured witha primary IP address.To enable a Virtual Router, use the following command in the INTERFACE mode. To delete a VRRPgroup, use the no vrrp-group vrid command in the INTERFACE mode.Figure 58-2.
