          DHCPv6 Options for Configuration of Softwire Address
                        and Port-Mapped Clients

Abstract

   This document specifies DHCPv6 options, termed Softwire46 options,
   for the provisioning of Softwire46 Customer Edge (CE) devices.
   Softwire46 is a collective term used to refer to architectures based
   on the notion of IPv4 Address plus Port (A+P) for providing IPv4
   connectivity across an IPv6 network.
