We call virtual private networks (VPNs) based on Multiprotocol Label
Switching (MPLS) 'MPLS VPN'.  This document discusses motivation and
a model of interworking among MPLS VPNs. It then proposes functional
capabilities for the interworking such as realization of security,
mapping of the QoS class, dynamic routing information distribution.
Considering easy provisioning, we focus on an interworking where each
MPLS network is once terminated and IP header look-up is executed at
an egress/ingress Label Switching Router (LSR), and IP over ATM
(RFC1483) is used for interworking connections.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
