Hi Mach,
many thanks for your review and the reference. Will study it in details. Will be glad to continue this work with you. Would you consider joining the authors?

Subject: RE: Two new drafts on (micro-)BFD over MC-LAG interfaces

Hi Greg and all,

I just have quick review on the drafts. If my understanding is correct, the idea is to use multicast destination address other than unicast address when  sending BFD packets over LAG links. And actually this idea has been proposed in (the predecessor of RFC 7130). And at that time, the co-authors of RFC 7130 did discuss the idea of using multicast destination address, but for some reason I forget now(I may need to reiterate the discussions on the archive), the idea was abandoned, although I still think multicast destination address is a smart idea.

Best regards,

Dear All,
two new drafts, related to RFC 7130, were published before the meeting:

*         BFD on MC-LAG interfaces in IP network<>

*         BFD on MC-LAG interfaces in IP/MPLS network<>

Greatly appreciate your reviews, comments, questions and suggestions.
