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.
