                   draft-ietf-mboned-v4v6-mcast-ps-00

Abstract

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

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
