Yes. But the DAD procedure confirmed that the link-local address was unique (at that point). That does not guarantee that the _EUI-64_ part of it is unique -- the mechanism is not using the whole link-local address here! No amount of DAD with LL unicast addresses is going to change this :-) This is mostly just a theoretical discussion, but the real point is -- there is no need to _specify_, using _standards action_ a deterministic mapping for the link-local multicast addresses. Just invent one and be done with it.. :-) -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
