Technical Summary

   When Segment Routing (SR) is used for building Network Resource
   Partitions (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.  This document describes how BGP-Link
   State (BGP-LS) with Multi-Topology (MT) can be used to distribute the
   information of SR based NRPs to the network controller when each NRP
   is associated with a separate logical network topology identified by
   a Multi-Topology ID (MT-ID).

Working Group Summary

   There was good support for this work in the IDR WG and some
   technical reviews which were addressed. There was consensus
   to publish this as informational document and no controversies.

Document Quality

   This is an informational document on how to use existing BGP-LS
   extensions developed by the IDR WG for a specific use case and 
   not a new protocol specification. There is no specific 
   information about deployments as specified in this document.

Personnel

   The Document Shepherd for this document is Susan Hares. The Responsible
   Area Director is Ketan Talaulikar.
