Failover operation

Failover operation involves handing off the VR's control of the virtual IP to another VR. Once a failover command is issued, the VR begins sending advertisements with priority zero instead of the configured priority. When the VR detects a peer VR taking control, it releases control of the virtual IP and ceases VR operation until a failback is executed. Failover occurs on only a backup VR operating as master.

If you specify the with-monitoring option, the VR continues to monitor the virtual IP after ceasing VR operation. If the master VR goes down, it then retakes control of the virtual IP.
