VRRP support

FortiController-5000 SLBC supports the Virtual Router Redundancy Protocol (VRRP), allowing you to configure HA between FortiController-5000 SLBC clusters using VRRP. You can also add a FortiControll-5000 SLBC cluster to a VRRP group with other VRRP routers.

You configure VRRP on the FortiController-5000 by creating a VRRP group and adding one or more FortiController front panel interfaces to the group. During normal operation, the primary FortiController sends outgoing VRRP routing advertisements. Both the primary and backup FortiControllers listen for incoming VRRP advertisements from other routers in the VRRP group. If the primary FortiController fails, the new primary FortiController takes over the role of both sending and receiving VRRP advertisements, maintaining the FortiController-5000 cluster within the VRRP group.
