Usage Guidelines
This command may be used to configure a VRRP router priority, advertisement interval, and preempt
mode.
The priority is used to determine which VRRP router takes over when the master fails over. A value of
255 is reserved for the router that is configured with the virtual router IP address. A value of 0 is
reserved for the master router's use to indicate it is releasing responsibility for the virtual router.
The advertisement interval specifies the interval between advertisements sent by the master router to
inform the backup routers that it is alive. The master down interval is the interval that a backup router
waits after the last received advertisement before it determines that the master router is down.
If you have an extremely busy CPU, a short dual master situation can occur. To avoid this, increase the
advertisement interval.
The preempt mode controls whether a higher priority backup router preempts a lower priority master.
allows preemption.
preempt
router that owns the virtual router IP address always preempts, independent of the setting of this
parameter.
