An LDP-based MAC address withdrawal mechanism is specified in [RFC4762] to remove dynamically learned MAC addresses when the source of those addresses can no longer forward traffic. This is accomplished by sending an LDP Address Withdraw Message with a MAC List TLV containing the MAC addresses to be removed from all other Provider Edge nodes over the LDP sessions. [RFC7361] describes an optimized MAC withdrawal mechanism that can be used to remove only the set of MAC addresses that need to be relearned in H-VPLS networks. [RFC7361] also describes optimized MAC withdrawal operations in PBB-VPLS networks.

Media Access Control (MAC) Address Withdrawal over Static Pseudowire
This document specifies a mechanism to signal Media Access Control (MAC) address withdrawal notification using a pseudowire (PW) Associated Channel (ACH). Such notification is useful when statically provisioned PWs are deployed in a Virtual Private LAN Service (VPLS) or Hierarchical Virtual Private LAN Service (H-VPLS) environment.
