Configuring VRRP
DETAILED STEPS
Disabling Preemption
You can disable preemption for a VRRP group member. If you disable preemption, a higher-priority back
up router will not take over for a lower-priority master router. Preemption is enabled by default.
BEFORE YOU BEGIN
Ensure that you have enabled the VRRP feature (see the “Configuring VRRP” section on page 20-7).
