Abstract:
=0A
 
=0A
 &nbs= p; Enhanced VPNs aim to deliver VPN services with enhanced
=0A
&n= bsp;  characteristics, such as guaranteed resources, latency, jitter,= etc.,
=0A
   so as to support customers requirements f= or connectivity services
=0A
   with these enhanced cha= racteristics.  Enhanced VPN requires
=0A
   integr= ation between the overlay VPN connectivity and the
=0A
 &nbs= p; characteristics provided by the underlay network.  A Network Resou= rce
=0A
   Partition (NRP) is a subset of the network r= esources and associated
=0A
   policies on each of a co= nnected set of links in the underlay network.
=0A
   An= NRP could be used as the underlay to support one or a group of
=0A   enhanced VPN services.=0A
 
=0A
&n= bsp;  When Segment Routing is used as the data plane of NRPs, each NR= P can
=0A
   be allocated with a group of Segment Ident= ifiers (SIDs) to identify
=0A
   the topology and resou= rce attributes of network segments in the NRP.
=0A
   T= he association between the network topology, the network resource
=0A=
   attributes and the SR SIDs may need to be distributed to= a
=0A
   centralized network controller.  In some= network scenarios, each NRP
=0A
   can be associated w= ith a unique logical network topology.  This
=0A
  = ; document describes a mechanism to distribute the information of SR
= =0A
   based NRPs using BGP-LS with Multi-Topology (MT).=0A
