VRRP preemption

In a Backup router VR configuration, the virtual router priority defaults to 100. The priority for the configured Owner is automatically set to the highest value of 255.

When multiple Backup routers exist in a VR:
  • If the current Master fails and the highest-priority Backup is not available, VRRP selects the next-highest priority Backup to operate as Master.

  • If the highest-priority Backup later becomes available, it preempts the lower-priority Backup and takes over the Master function.

To remove this preemptive ability on a VR, disable it with the no preempt command.

Preemption applies only to VRRP routers configured as Backups.
