Multiple Ethernet - IPv6 address mapping
encapsulation - fixed prefixWIDE ProjectJapannaoki.matsuhira@gmail.comIPv6EthernetThis document specifies Multiple Ethernet - IPv6 address mapping
encapsulation - fixed prefix (ME6E-FP) base specification. ME6E-FP makes
expantion ethernet network over IPv6 backbone network with encapsuation
technoogy. And also, E6ME-FP can stack multiple Ethernet networks.
ME6E-FP work on own routing domain.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.This document provides Multiple Ethernet - IPv6 address mapping
encapsulation - fixed prefix (ME6E-FP) base specification.ME6E-FP make many virtual ethernet network over IPv6 network with
unicast base technology.ME6E-FP can use on own routing domain, i.e. can advertise routes to
the network. shows network configuration with
ME6E-FP. The network consists of three parts. IPv6 network, Nodes (Host
or Router) , and ME6E-FP.Backbone network is operated with Dual Stack or IPv6 only. Node may
physical node or virtual node, and have Ethernet Interface.ME6E-FP connects IPv6 network and nodes. ME6E-FP connect to node with
Ethernet (Layer2), and ME6E-FP connect to IPv6 network with IPv6
(Layer3).ME6E-FP has mainly two function. One is encapsulate from Ethernet
frame to IPv6 packet, and decapsulate from IPv6 packet to Ethernet
frame. Another is advertise route corresponding to Ethernet MAC
address.ME6E-FP encapsulates ethernet frame to IPv6 packet from node to
IPv6 network, and decapsulates IPv6 packet to ethernet frame from IPv6
network to node. shows encapsulation and
decapsulation of Ethernet frame and IPv6 packetThe value of next header field of IPv6 header is TBD. The value of
EtherIP may used, however new value for
this protocol may assigned.When encapsulated IPv6 Packet size exceed path MTU , ME6E-FP
fragment Ethernet frame, and then send them.ME6A is a IPv6 address used in
outer IPv6 header which encapsulate ethernet frame by ME6E-FP. shows ME6A architectureME6 address consists of three parts as follows.ME6
address prefix . This value is preconfigured to all ME6E-FP in the
IPv6 networks.Multiple network plane ID is an identifier of
Ethernet network over IPv6 backbone network. This value is
preconfigured depend on the ME6E-FP belong which ethernet network
plane. This value is just like VLAN-ID of IEEE802.1Q, tag
VLAN.Ethernet
MAC address in inner Ethernet frame. EUI-48 address or EUI-64
address.ME6 address is resolved by copying ethernet MAC address in inner
ethernet frame, and preconfigured values, ME6 prefix and multiple
network plane ID.ME6E-FP advertises ME6 address host route to the IPv6 network. The
number of the route of ME6 addresses is the same as the number of MAC
address table.In the IPv6 network, usual dynamic routing protocol for IPv6 can be
used such as RIPng, OSPFv3 and IS-IS
.ME6E-FP can be used closely in the IPv6 network, so ME6 address does
not be advertised outside of the IPv6 network, and IPv6 packet which
contains ME6 address does not be forwarded outside of the backbone
network.So, ME6 address format and ME6 address prefix can be decided each
IPv6 network. Some example are shown as follows. These address is based
on EUI-48 MAC address. EUI-64 address is the future study.This example is based on IPv6 Global Unicast
Address Format. shows IPv6 Global Unicast Address

co-existing. And also, ME6 address prefix may renumber, that mean,
small start with 16bits plane ID ME6 address, then renumber to 32bits
plane ID ME6 address.ME6E-FP provide flexible operation for scalability of multiple
network plane id.Configuration of ME6E-FP require just three information, ME6 address
prefix, multiple Network plane ID, and prefix length of ME6E-FP route.
These information could explain just only one line, "<ME6E-FP address
prefix><multiple network plane ID>/ prefix length of ME6E-FP
route".ME6E-FP has following useful characteristics.can operate unicast routing domainTBDThis document makes no request of IANA if using EtherIP Header.Note to RFC Editor: this section may be removed on publication as an
RFC.ME6E-FP use automatic tunneling technologies. Security consideration
related tunneling technologies are discussed in RFC2893, RFC2267,
etc.Multiple Ethernet - IPv6 mapped IPv6 address (ME6A)XX
