Usage Guidelines

The preempt option enables a higher-priority backup router to preempt a master with a lower priority. When a VRRP enabled router receives a lower priority VRRP advertisement and preemption is enabled, the higher-priority VRRP enabled router takes over as master. The new master starts sending VRRP advertisements and the old, lower-priority master relinquishes mastership.



The router that owns the virtual IP address always preempts, independent of the setting of this parameter.

When a VRRP enabled router preempts the master, it does so in one of the following ways:
  • If the preempt delay timer is configured for between 1 and 3600 seconds and the lower-priority master is still operating, the router preempts the master when the timer expires.

  • If the preempt delay timer is configured for 0, the router preempts the master after 3 times the hello interval.

  • If the higher priority router stops receiving advertisements from the current master for 3 times the hello interval, it takes over mastership immediately.


    The preempt feature can be disabled with the configure vrrp vlan vrid dont-preempt command.


The following command allows preemption:

configure vrrp vlan vlan-1 vrid 1 preempt
