The IESG has received a request from the Layer 2 Virtual Private Networks WG (l2vpn) to consider the following document: - 'LDP Extensions for Optimized MAC Address Withdrawal in H-VPLS' <draft-ietf-l2vpn-vpls-ldp-mac-opt-11.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-04-08. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract RFC4762 describes a mechanism to remove or unlearn MAC addresses that have been dynamically learned in a Virtual Private LAN Service (VPLS) Instance for faster convergence on topology change. The procedure also removes MAC addresses in the VPLS that do not require relearning due to such topology change. This document defines an enhancement to the MAC Address Withdrawal procedure with empty MAC List from RFC4762, which enables a Provider Edge(PE) device to remove only the MAC addresses that need to be relearned. Additional extensions to RFC4762 MAC Withdrawal procedures are specified to provide optimized MAC flushing for the Provider Backbone Bridging (PBB)VPLS specified in RFC7041.
