Multiple Ethernet - IPv6 mapped IPv6 address (ME6A)

Internet-Draft	ME6A	April 2024
Matsuhira	Expires 6 October 2024	[Page]

Abstract

This document specifies Multiple Ethernet - IPv6 mapped IPv6 address(ME6A) spefification. ME6A is an Ethernet-mapped IPv6 address with a plane ID. Unique allocation of plane id value enables duplicated MAC address unique in IPv6 address space. This address may use Ethernet over IPv6 encapsulation.¶

1. Introduction

This document specifies Multiple Ethernet - IPv6 mapped IPv6 address(ME6A) spefification. ME6A is an Ethernet-mapped IPv6 address with a plane ID. Unique allocation of plane ID value enables 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.¶
Ethernet plane ID: Ethernet network plane ID is the network identification of Ethernet network plane.¶
Ethernet address: Ethernet MAC address. EUI-48 address or EUI-64 address.¶

3. IANA Considerations

This document does not request IANA.¶

Note to RFC Editor: this section may be removed on publication as an RFC.¶
