Command Syntax

Command Mode
Router configuration
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
