RFC 2462 says that the node MUST join the solicited-node multicast group (which implies using MLD) when performing DAD.
Since the node has to send an MLD report in the first instance, there's no reason not to follow the rest of the MLD specification.

MLD-snooping switches is the biggest reason.
Ok. So, it seems like there would be no need to send these reports for link-local multicast on point-to-point links. Should this clarification be made in the IPv6 over PPP RFC?
thanks, Siva

RFC2710 (MLD) states that when a General Membership Query is received, a node listening to the query sends a membership report for all multicast addresses it is listening to, excluding the all-nodes link-local multicast address and any multicast addresses of scope 0 (reserved) and 1 (node-local).
My question is, is the node required to send the membership report for solicited-node multicast address as well? In general, since nodes do not receive link-local scope multicast packets from out side the link, why is it required for the nodes to report membership to the router for *any* link-local scope multicast addresses?
Thanks,
Siva
