# Configure Switch A to work in preemptive mode, so that it can become the master whenever it works
normally. Configure the preemption delay as five seconds to avoid frequent status switchover.

# Set VLAN interface 3 on Switch A to be tracked, and configure the amount by which the priority value
decreases to be more than 10 (30 in this example), so that when VLAN-interface 3 fails, the priority of
Switch A in VRRP group 1 decreases to a value lower than 100 and thus Switch B can become the
master.
