Abstract:

   An NRP is a subset of the network resources and associated policies
   on each of a connected set of links in the underlay network.  An NRP
   could be used as the underlay to support one or a group of enhanced
   VPN services, which provide advanced features such as guaranteed
   resources, bounded latency or jitter to meet specific customer
   connectivity requirements.

   When Segment Routing (SR) is used for building NRPs, each NRP can be
   allocated with a group of Segment Identifiers (SIDs) to identify the
   topology and resource attributes of network segments in the NRP.  In
   some network scenarios, each NRP can be associated with a unique
   logical network topology.  When a centralized network controller is
   used for NRP-specific constraint-based path computation, especially
   when an NRP spans multiple IGP areas or multiple Autonomous Systems
   (ASes), BGP-LS is needed to advertise the NRP topology and associated
   resource information to the network controller.  This document
   describes a mechanism to distribute the information of SR based NRPs
   using BGP-LS with MT.
