A new Request for Comments is now available in online RFC libraries. RFC 5747 Title: 4over6 Transit Solution Using IP Encapsulation and MP-BGP Extensions Author: J. Wu, Y. Cui, X. Li, M. Xu, C. Metz Status: Experimental Date: March 2010 Mailbox: jianping@cernet.edu.cn, cy@csnet1.cs.tsinghua.edu.cn, xing@cernet.edu.cn, xmw@csnet1.cs.tsinghua.edu.cn, chmetz@cisco.com Pages: 15 Characters: 33768 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-wu-softwire-4over6-04.txt URL: http://www.rfc-editor.org/rfc/rfc5747.txt 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.
