Abstract:
   Enhanced VPN (VPN+) aims to provide enhanced VPN service to support
   some applications' 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.

   When Segment Routing is used as the data plane of VTNs, each VTN can
   be allocated with a group of Segment Identifiers (SIDs) to identify
   the topology and resource attributes of network segments in the VTN.
   The association between the network topology, the network resource
   attributes and the SR SIDs may need to be distributed to a
   centralized network controller.  In network scenarios where each VTN
   can be associated with a unique logical network topology, this
   document describes a mechanism to distribute the information of SR
   based VTNs using BGP-LS with Multi-Topology.
