Usage
The advertisements being sent by the master virtual router communicate the state and priority of the
current master virtual router.
The advertisement-interval command configures the time between successive advertisement packets
and the time before other routers declare the master router to be down. Routers or access servers on
which timer values are not configured can learn timer values from the master router. The timers
configured on the master router always override any other timer settings. All routers in a VRRP group
must use the same timer values. If the same timer values are not set, the routers in the VRRP group will
not communicate with each other and any misconfigured router will change its state to master.
Examples
The following example shows how to configure the master virtual router to send advertisements every 4
seconds:
router vrrp 1
advertisement-interval 4
