Technical Summary

     This document specifies an extension to the multicast addressing
     architecture of the IPv6 protocol. The extension allows for the use
     of Interface Identifiers (IIDs) to allocate multicast addresses.
     When a link-local unicast address is configured at each interface
     of a node, an IID is uniquely determined.  After that, each node
     can generate their unique multicast addresses automatically without
     conflicts.  Basically, this document proposes an alternative method
     for creating link-local multicast addresses over a known method
     like unicast-prefix-based IPv6 multicast addresses. It is preferred
     to use this method for link-local scope rather than unicast-
     prefix-based IPv6 multicast addresses.  This memo update RFC3306.
