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.
Change that advertisement interval with the following command in the VRRP mode:
Figure 59-12. Command Example: advertise-interval
Figure 59-13. Command Example Display: advertise-interval in VRID mode
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.
