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.
