advertisement-interval (VRRP)

Configures the interval at which the master VRRP router advertises its existence to the backup routers.

Syntax

advertisement-interval range

Command Default

The default is 1 second for version 2, 1000 milliseconds for version 3.

Parameters

range: Interval at which the master VRRP router advertises its existence to the backup routers. Valid values range from 1 through 255 seconds for VRRPv2 and from 1000 through 40900 milliseconds for VRRPv3.

Modes

Virtual-router-group configuration mode

Usage Guidelines

This interval is the length of time, in seconds, between each advertisement sent from the master to its backup VRRP routers. The advertisement notifies the backup routers that the master is still active. If the backup routers do not receive an advertisement from the master in a designated amount of time, the backup with the highest priority can assume the role of master.

This command can be used for either VRRP or VRRP-E and for VRRPv3 and VRRP-Ev3.

Examples

To set the advertisement interval to 30 seconds for VRRP-E group 10:

device# configure terminal
device(config)# interface ve 25
device(config-ve-25)# vrrp-extended-group 10
device(config-vrrp-extended-group-10)# advertisement-interval 30

To set the advertisement interval to 3000 milliseconds for VRRP-Ev3 group 19:

device# configure terminal 
device(config)# interface ve 2019
device(config-ve-2019)# ipv6 vrrp-extended-group 19 
device(config-vrrp-extended-group-19)# advertisement-interval 3000
