IPv6 Multicast Address With Embedded IPv4 Multicast Address
draft-ietf-mboned-64-multicast-address-format-05
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.
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].
