	If there is time on the agenda I'd like to raise/have a discussion on 
dlep support for IP multicast.  These questions come out of looking at 
the opensource dlep implementation posted at 
https://github.com/mit-ll/LL-DLEP and RFC8175.  The questions are:

(a) How does a multicast receiver identify itself (and remove itself)

(b) how does a (potential) multicast sender know about a multicast group
and it's related parameters

(c) how does a (potential) multicast sender know what endpoints are
reachable via a multicast group

I raised this same question with a number of people including the 
RFC8175 authors and we generally agreed that there are answers for (a) 
and (b) that can be traced easily/obviously back to RFC8175, and a 
fairly straight forward answer to (c) that we don't think falls within 
the intent of the RFC. (At least the authors of RFC8175 gave the same 
answers that we separately arrived at.)

I think it would be great if we could review the questions and ensure 
that we all agree on the answers.  I can through some slides together on 
this, or we Stan/Rick could do the same. - Or we can start with Stan's 
(if he prefers) email on the topic.
