Change the Advertisement Interval

By default, the MASTER router transmits a VRRP advertisement to all members of the VRRP group every
1 second, indicating it is operational and is the MASTER router. If the VRRP group misses three
consecutive advertisements, the election process begins and the BACKUP virtual router with the highest
priority transitions to MASTER.
Note: Dell Force10 recommends increasing the VRRP advertisement interval to a value higher
than the default value of 1 second to avoid throttling VRRP advertisement packets. If you do
change the time interval between VRRP advertisements on one router, you must change it on all
participating routers.
To change that advertisement interval, use the following command in the VRRP mode:
