Change The Advertisement Interval - Dell Force10 C150 Configuration Manual

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.
Change that advertisement interval with the following command in the VRRP mode:
