The IESG has received a request from the Bidirectional Forwarding Detection WG (bfd) to consider the following document: - 'Bidirectional Forwarding Detection (BFD) on Link Aggregation Group (LAG) Interfaces' <draft-ietf-bfd-on-lags-02.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 2013-12-02. 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 This document proposes a mechanism to run BFD on Link Aggregation Group (LAG) interfaces. It does so by running an independent Asynchronous mode BFD session on every LAG member link. This mechanism allows the verification of member link continuity, either in combination with, or in absence of, LACP. It provides a shorter detection time than what LACP offers. The continuity check can also cover elements of layer 3 bidirectional forwarding. This mechanism utilizes a well-known UDP port distinct from that of single-hop BFD over IP. This new UDP port removes the ambiguity of BFD over LAG packets from BFD over single-hop IP.
