This document provides requirements for Layer 3 Virtual Private
Networks (L3VPNs).  It identifies requirements applicable to a number
of individual approaches that a Service Provider may use to provision
a Virtual Private Network (VPN) service.  This document expresses a
service provider perspective, based upon past experience with IP-based
service offerings and the ever-evolving needs of the customers of such
services.  Toward this end, it first defines terminology and states
general requirements.  Detailed requirements are expressed from a
customer perspective as well as that of a service provider.

This document is a product of the Layer 3 Virtual Private Networks
Working Group of the IETF.
