Several types of Carrier-Grade-NATs (CGNs) 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 (i.e. tunnels) 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 CPE (Customer Premises Equipment) discovers the remote
softwire concentrator or CGN in a hub and spoke network using DHCP.
Based on two new Softwire Concentrator or CGN Discovery DHCP Options,
proposed in the document, a user can obtain softwire concentrator or
CGN information and then set up a tunnel to the softwire concentrator
or CGN.
