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 3 consecutive
advertisements, then the election process begins and the BACKUP virtual router with the highest priority
transitions to MASTER.

Note: Dell Force10 recommends you to increase 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.
