Router Redundancy Protocol (VRRP) group, use the advertisement-interval command in router
configuration mode. To restore the default value, use the no form of this command.


Command Syntax

advertisement-interval interval
no advertisement-interval

interval

Time interval between successive advertisements by the master virtual router. The
unit of the interval is in seconds. The default is 1 second. The valid range is 1 to 255
seconds.


Default

Default interval is 1 second.


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
