Network Working Group N. Matsuhira Internet-Draft WIDE Project Intended status: Informational 4 April 2023 Expires: 6 October 2023 Multiple Ethernet - IPv6 mapped IPv6 address (ME6A) draft-matsuhira-me6a-14 Abstract This document specifies Multiple Ethernet - IPv6 mapped IPv6 address(ME6A) spefification. ME6A is Ethernet mapped IPv6 address with plane ID. Unique allocation of plane id value enable duplicated MAC address unique in IPv6 address space. This address may use Ethernet over IPv6 encapsulation. 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]. Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF).

Introduction This document specifies Multiple Ethernet - IPv6 mapped IPv6 address(ME6A) spefification. ME6A is Ethernet mapped IPv6 address with plane ID. Unique allocation of plane ID value enable duplicated MAC address unique in IPv6 address space. This address may use Ethernet over IPv6 encapsulation such as Multiple Ethernet - IPv6 mapping encapsulation - fixed prefix (ME6E- FP) [I-D.draft-matsuhira-me6e-fp] and Multiple Ethernet - IPv6 mapping encapsulation - prefix resolution (ME6E- PR)[I-D.draft-matsuhira-me6e-pr]. 2. ME6A architecture Figure 1 shows ME6A architecture. | 128 - m -n bits | m bits | n bits | +-----------------------+----------------------+------------------+ | ME6A prefix | Ethernet plane ID | Ethernet address | +-----------------------+----------------------+------------------+ Figure 1 ME6A consists of three parts as follows. ME6A prefix ME6A prefix. This value is fixed value with M46E-FP, and non fixed value with M46E-PR.
