This document describes an implementation strategy for BGP/MPLS IP
Virtual Private Networks (VPNs) in which the outermost MPLS label
(i.e., the tunnel label) is replaced with either an IP header or an
IP header with Generic Routing Encapsulation (GRE).
The implementation strategy described herein enables the deployment
of BGP/MPLS IP VPN technology in networks whose edge devices are MPLS
and VPN aware, but whose interior devices are not. This memo provides information for the Internet community.
This document is a product of the Layer 3 Virtual Private Networks
Working Group of the IETF.
