Abstract

Due to the lack of IPv4 address space, more and more IPv6 networks have been deployed not only on edge networks but also on backbone networks. However, there are still a large number of legacy IPv4 hosts and applications. As a result, IPv6 networks and IPv4 applications/hosts will have to coexist for a long period of time.

   4over6 Transit Solution Using IP Encapsulation and MP-BGP Extensions

Abstract

   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.
