Right, MLD is a host-router protocol.
Routers among them speak a routing protocol, so they wouldn’t exchange MLD.
(A RPL “leaf” is a router.)

> Finally I'm looking at BIER see how their ideas could apply to LLNs…

Yep.  
We (TZI) have done (specified, implemented, analyzed) an efficient BIER-like multicast forwarding protocol for non-storing mode a while ago.
Need to write that up in an I-D and submit it somewhere.
BIER or ROLL or both?
