Abstract:
   Enhanced VPN (VPN+) aims to provide enhanced VPN service to support
   some application's needs of enhanced isolation and stringent
   performance requirements.  VPN+ requires integration between the
   overlay VPN and the underlay network.  A Virtual Transport Network
   (VTN) is a virtual underlay network which consists of a subset of the
   network topology and network resources allocated from the physical
   network.  A VTN could be used as the underlay for one or a group of
   VPN+ services.

   In some network scenarios, each VTN can be associated with a unique
   logical network topology.  This document describes a mechanism to
   build the SR based VTNs using IS-IS Multi-Topology together with
   other well-defined IS-IS extensions.
