Because preempt is enabled by default, disable the preempt function with the following command in the
VRRP mode. To re-enable preempt, use the

show commands because it is a default setting.

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.
To change that advertisement interval, use the following command in the VRRP mode:
Task Command Syntax Command Mode
Prevent any BACKUP router with a higher priority
from becoming the MASTER router.

INTERFACE-VRID
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.
