1.  Introduction

   Mapping of Address and Port (MAP) defined in [I-D.ietf-softwire-map]
   is a mechanism for providing IPv4 connectivity service to end users
   over a service provider's IPv6 network, allowing for shared or
   dedicated IPv4 addressing.  It consists of a set of one or more MAP
   Border Relay (BR) routers, responsible for stateless forwarding, and
   one or more MAP Customer Edge (CE) routers, that collectively form a
   MAP Domain when configured with common MAP rule-sets.  In a
   residential broadband deployment the CE is sometimes referred to as a
