          IPv4-IPv6 Multicast: Problem Statement and Use Cases
                   draft-ietf-mboned-v4v6-mcast-ps-04

Abstract

   This document discusses issues and requirements raised by intra-
   domain IPv4-IPv6 multicast interconnection and co-existence
   scenarios.  It also discusses various multicast use cases which may
   occur during IPv6 transitioning.
