Configuration manual

Virtual Router Redundancy Protocol (VRRP) | 1151

Disable Preempt

The preempt command is enabled by default, and it 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.

Since preempt is enabled by default, disable the preempt function with the following command in the

VRRP mode. Re-enable preempt by entering the preempt command. When preempt is enabled, it does not

display in the show commands, because it is a default setting.,

Figure 59-10. Command Example: no preempt

Figure 59-11. Command Example Display: show config in VRID mode

Note: All virtual routers in the VRRP group must be configured the same: all configured with preempt

enabled or configured with preempt disabled.

Task Command Syntax Command Mode

Prevent any BACKUP router with a higher priority

from becoming the MASTER router.
