Description
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.Note:By default, a higher-priority backup router can preempt a lower-priority primary router.
no-preempt—Prohibit the preemption of the primary router. Whenno-preemptis 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.
Default
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.
