Several types of Carrier Grade NATs have been proposed to simplify
IPv4/IPv6 transition of the edge network by integrating tunnels and
NAT. A very common scenario is that many users set up softwires to a
softwire concentrator for public or private access services. In order
to establish softwires successfully, a new mechanism is required to
enable users in the edge network to discover the information of the
concentrator. This document describes how a host or Customer Premises
Equipment discovers the remote softwire concentrator or CGN in a hub
and spoke network using DHCP. Based on two new Softwire Concentrator
Discovery DHCP Options, proposed in the document, a user can obtain
the information of the softwire concentrator or CGN and then set up a
tunnel to it.
