Technical Summary

   This document specifies a Gateway-Initiated Dual-Stack lite
   (GI-DS-lite) applicable to certain tunnel-based access
   architectures. GI-DS-lite extends existing access tunnels beyond
   the access gateway to an IPv4-IPv4 NAT using softwires.

Working Group Summary

   This document was discussed in depth and well-reviewed. The overall
   WG consensus is strong to publish this document.
