Abstract

   This document specifies M46E Prefix Resolution (M46E-PR)
   specification.  M46E-PR connect IPv4 stub networks between IPv6
   backbone network.  And also, M46E-PR can stack many IPv4 networks,
   i.e. the nwtworks using same IPv4 private addresses without
   interdependence.

1.  Introduction

   This document provide M46E Prefix Resolution (M46E-PR) specification.

   The basic strategy for IPv6 deployment is dual stack.  However,
   because of exhaustion of IPv4 address, there will be no IPv4
   addresses for configuring dual stack in near future.  That means
   there will be IPv6 only networks automatically.

   However, there are many IPv4 only networks still exist and those
   seems continuous use in near future.  That means methods continuous
   use of IPv4 network over IPv6 only network will be required.

   M46E-PR also provide such methots.

2.  Basic Network Configuration

   Figure 1 shows network configuration with M46E-PR.  The network
   consists of three parts, backbone network, stub network, and M46E-PR.

   Backbone network can be operated with IPv6 only.  Stub network has
