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.
Dell(conf-if-te-1/1-vrid-111)#show conf

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.
If are using VRRP version 2, you must configure the timer values in multiple of whole seconds. For
example a timer value of 3 seconds or 300 centisecs are valid and equivalent. However, a time value of
50 centisecs is invalid because it not a multiple of 1 second. If you are using VRRP version 3, you must
configure the timer values in multiples of 25 centisecs.
If you are configured for VRRP version 2, the timer values must be in multiples of whole seconds. For
example, timer value of 3 seconds or 300 centisecs are valid and equivalent. However, a timer value of
50 centisecs is invalid because it not is not multiple of 1 second.
If are using VRRP version 3, you must configure the timer values in multiples of 25 centisecs.
To change the advertisement interval in seconds or centisecs, use the following command. A centisecs is
1/100 of a second.
• Change the advertisement interval setting.
