Virtual Router Redundancy Protocol (VRRP) | 1137
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 58-10. Command Example: no preempt
Figure 58-11. 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.
