Configuring the VRRP Router Advertisement Interval
To configure the VRRP router advertisement interval, use the following command:
configure vrrp vlan vlan_name vrid vridval advertisement-interval interval [{seconds} | centiseconds]

Note
We recommend that you configure the same router advertisement interval in all VRRP routers. VRRPv3 supports a 40 second maximum advertisement interval.
Note
If the advertisement interval is different on the master and backup switches, the master switch's advertisement interval is used by the backup as well.
