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.
