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 a network controller in a specific context where each NRP is associated with a separate logical topology identified by a Multi-Topology ID (MT-ID). This document sets out the targeted scenarios for the approach suggested, and presents the scalability limitations that arise.}, }
