Release Information
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS 11.3 for the QFX Series.
Description
In a Virtual Router Redundancy Protocol (VRRP) configuration, determine whether or not a backup router can preempt a master router:
- preempt—Allow the master router to be preempted.
Note: By default, a higher-priority backup router can preempt a lower-priority master router.
- no-preempt—Prohibit the preemption of the master router. When no-preempt is configured, the backup router cannot preempt the master router even if the backup router has a higher priority.
The remaining statement is explained separately.
Default
By default the preempt statement is enabled, and a higher-priority backup router preempts a lower-priority master router even if the preempt statement is not explicitly configured.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
