The output shows that when Ethernet 1/2 on Router A fails, the weight of the AVF on Router A
decreases to 5, which is lower than the lower limit of failure. All VFs on Router A turn to initialized
state and cannot be used for packet forwarding. The VF corresponding to MAC address
000f-e2ff-0011 on Router C becomes the AVF, and Router C takes over Router A for packet
forwarding.
