Examples of Disabling Preempt
Re-enable preempt by entering the preempt command. When you enable preempt, it does not display in the
show commands, because it is a default setting.
The following example shows how to disable preempt using the no preempt command.
Dell(conf-if-te-1/1)#vrrp-group 111
Dell(conf-if-te-1/1-vrid-111)#no preempt
Dell(conf-if-te-1/1-vrid-111)#
The following example shows how to verify preempt is disabled using the show conf command.

Changing the Advertisement Interval
By default, the MASTER router transmits a VRRP advertisement to all members of the VRRP group every one
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
: To avoid throttling VRRP advertisement packets, Dell Networking OS recommends increasing the
VRRP advertisement interval to a value higher than the default value of one second. If you do change the
time interval between VRRP advertisements on one router, change it on all participating routers.
To change the advertisement interval, use the following command.
• Change the advertisement interval setting.
