Disabling Preempt

The preempt command is enabled by default. The command forces the system to change the MASTER router if another router with a higher priority comes online.

Prevent the BACKUP router with the higher priority from becoming the MASTER router by disabling preempt.
NOTE You must configure all virtual routers in the VRRP group the same: you must configure all with preempt enabled or configure all with preempt disabled.

Because preempt is enabled by default, disable the preempt function with the following command.

Prevent any BACKUP router with a higher priority from becoming the MASTER router.
INTERFACE-VRID mode
no preempt

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.

DellEMC(conf-if-gi-1/1)#vrrp-group 111
DellEMC(conf-if-gi-1/1-vrid-111)#no preempt
DellEMC(conf-if-gi-1/1-vrid-111)#

The following example shows how to verify preempt is disabled using the show conf command.

DellEMC(conf-if-gi-1/1-vrid-111)#show conf
