Hi Jeff, Reshad, John, et. al, at our discussion in Berlin <https://www.ietf.org/proceedings/96/minutes/minutes-96-bfd> John pointed to recent extension of IEEE 802.1AX, Distributed Resilient Network Interface (DRNI). I've reviewed, to the best of my understanding, Section 9 in IEEE 802.1AX-2014 (I can send copy if anyone is interested) and I agree with John that MC-LAG can be viewed as special case of DRNI. But I'm not sure that trying to address monitoring of DRNI with BFD would be appropriate. I think that using CFM/G.8013, a.k.a. Y.1731 mechanisms to monitor Layer 2 entity, which DRNI is, seems more appropriate. If there are cases of DRNI, other then MC-LAG, that are of interest to IETF community, I'd certainly would like to discuss these and see how we can apply BFD to monitor them as unified entity as well as its individual interfaces, similar to RFC 7130.
