15.2.7 Configuring automatic switch-back suppression

Automatic switch-back operates by default.If a backup virtual router takes over a failed master virtual router and then the previous master is restored, the previous master (now a backup) automatically takes over as the current master because it has a higher priority than the current master. If you suppress this automatic switch-back, the backup virtual router with a higher priority than the master virtual router will not automatically take over the master virtual router.

Points to note

Suppress automatic switch-back on the master virtual router that is not the IP address owner.
