Abstract

   This document provides a framework for the operation and management
   of Layer 3 Virtual Private Networks (L3VPNs).  This framework intends
   to produce a coherent description of the significant technical issues
   that are important in the design of L3VPN management solutions.  The
   selection of specific approaches, and making choices among
   information models and protocols are outside the scope of this
   document.

1.  Introduction

1.1.  Terminology

   In this document, the following terms are used and defined as
   follows:

   VPN:

      Virtual Private Network.  A set of transmission and switching
      resources that will be used over a shared infrastructure to
      process the (IP) traffic that characterizes communication services
      between the sites or premises interconnected via this VPN.  See
      [RFC4026].

   L3VPN:

      An L3VPN interconnects sets of hosts and routers based on Layer 3
      addresses.  See [RFC4026].

   VPN Instance:

      From a management standpoint, a VPN instance is the collection of
      configuration information associated with a specific VPN, residing
