You can configure VRRP to track active VLANs (active ports in a VLAN or Loopback) of up to eight specified VLANs as criteria for failover.
If no active ports remain on the specified VLANs, the router automatically relinquishes master status based on the tracking mode.
When a tracking condition is in a failed state, VRRP behaves as though it is locally disabled; so it is neither master nor backup (which are both active states).
