preempt (VRRP)


Hierarchy Level


In a Virtual Router Redundancy Protocol (VRRP) configuration, determine whether or not a backup router can preempt a primary router:

  • preempt—Allow the primary router to be preempted.


    By default, a higher-priority backup router can preempt a lower-priority primary router.

  • no-preempt—Prohibit the preemption of the primary router. When no-preempt is configured, the backup router cannot preempt the primary router even if the backup router has a higher priority.

The remaining statement is explained separately. See CLI Explorer.


By default the preempt statement is enabled, and a higher-priority backup router preempts a lower-priority primary router even if the preempt statement is not explicitly configured.
