After you configure the function, a VSI deletes the MAC address of the PW carried in a received MAC Withdraw message carrying 0x404 TLV but retains the MAC addresses of the other PWs and AC interfaces.
In the scenario where a CE accesses an L2VPN network, when the AC between the CE and its connected PE becomes faulty frequently, the PE will generate a large number of MAC Withdraw messages carrying 0x404 TLV. After receiving these MAC Withdraw messages, the VSI of the remote PE will frequently clear MAC address information. If the VSI has many PWs, traffic will be broadcast for a long period, wasting device bandwidth. To resolve the issue, configure the function of clearing the MAC addresses of specific PWs.
