The emerging and growing deployment of IPv6 networks will introduce
cases where connectivity with IPv4 networks crossing IPv6 transit
backbones is desired.  This document describes a mechanism for
automatic discovery and creation of IPv4-over-IPv6 tunnels via
extensions to multiprotocol BGP.  It is targeted at connecting
islands of IPv4 networks across an IPv6-only backbone without the
need for a manually configured overlay of tunnels.  The mechanisms
described in this document have been implemented, tested, and
deployed on the large research IPv6 network in China.  This document
defines an Experimental Protocol for the Internet community.

This document is an Independent Submission.
