backup-advertisement-interval

Configures the interval at which backup VRRP routers advertise their existence to the master router.

Syntax

backup-advertisement-interval interval

Command Default

The default backup advertisement-interval is 60 seconds.

Parameters

interval
Interval at which a backup VRRP router advertises its existence to the master router. Valid values range from 60 through 3600 seconds.

Modes

Virtual-router-group configuration mode

Usage Guidelines

The interval is the length of time, in seconds, between each advertisement sent from the backup routers to the master router. The advertisement notifies the master router that the backup is still active. If the master router does not receive an advertisement from the backup 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.

Examples

To set the backup advertisement interval to 120 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)# backup-advertisement-interval 120
