This document describes some methods which may be used by Service Providers
to provide Virtual Private Networks for some scenarios where the Service
Provider's network or Customer's network is comprised of part of IPv4
network and part of IPv6 network.These situations can't be avoided during
the process of IPv4 transition to IPv6, e.g. IPv6 backbone network for
IPv4-IPv6 hybrid VPN sites,or IPv4 backbone network for IPv4-IPv6 hybrid
VPN sites,or IPv4-IPv6 hybrid backbone network for IPv4-IPv6 hybrid VPN
sites.This proposal continue to use the concepts described in the Internet
draft 'BGP/MPLS VPN'[2547bis],such as RD,VRF,Route Target and some
mechanisms. In BGP/MPLS VPN, MPLS is used to forward packets over the
backbone, and "Multiprotocol BGP" is used for distributing VPN routes over
the service provider backbone.
