You still need ND to provide the link-layer address resolution (i.e. the IPv6 equivalent of ARP), even with DHCPv6. Moreover, how do you come to the conclusion that DHCPv6, which uses multicast for the solicitation, is more reliable over links where multicast is unreliable? FYI, I have been using SLAAC over 802.11 for many years, and have supported large 802.11 installations with SLAAC and have never had a problem related to "unreliable multicast" on that medium. Other problems, yes. But not that one. michael
