Hi Greg and all,

 

I just have quick review on the drafts. If my understanding is co= rrect, 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 https://tools.ietf.org/html/draft-chen-bfd-interface-00 (the prede= cessor 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 thin= k multicast destination address is a smart idea.

 

Best regards,

Mach
