      IPv6 Multicast Address With Embedded IPv4 Multicast Address
            draft-ietf-mboned-64-multicast-address-format-06

Abstract

   This document reserves one bit (M-bit) of the unicast prefix-based
   multicast IPv6 address for ASM and an IPv6 multicast prefix for SSM
   mode to be used in the context of IPv4-IPv6 interconnection.

   The document specifies an algorithmic translation of an IPv6
   multicast address to a corresponding IPv4 multicast address, and vice
   versa.  This algorithmic translation can be used in both IPv4-IPv6
   translation or encapsulation schemes.

   This document updates RFC 7371.

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].
