Thomas, thank you for the reply.

Link-layer multicast mechanisms are used in any autoconfing (DHCPv6,
SLAAC, probably more) mechanism.

A stack booting up sends packets to multicast destinations.

MANET already allocates a multicast address for this.

Suffices it to mention it.

Otherwise leave place for non-understanding: will the IPv6 autoconf
stack use the MANET multicast address?  Or the other non-MANET multicast
address?

I mostly agree with you.

And there are two different people here (Teco, myself) saying
approximately the same thing about multicast.  The autoconf group is not
large.  Are two opinions worth ignoring?
