it works correctly; configure the preemption delay as 5 seconds to avoid frequent status
switchover.

# Create track entry 1 to associate with the physical status of VLAN-interface 3 on Switch A. When
the track entry becomes negative, it means that the interface fails.

# Configure VF tracking to monitor track entry 1 and specify the value by which the weight
decreases, making the weight of Switch A decrease by more than 245 (250 in this example) when
track entry 1 turns to negative. In such a case, another router with a higher weight can take over.
