Configures the interval at which backup VRRP routers advertise their existence to the master router.
The default backup advertisement-interval is 60 seconds.
Virtual-router-group configuration mode
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.
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
