Operations, Administration and Maintenance (OAM) for Network Resource Partition (NRP) in SR

A Network Resource Partition (NRP) represents a subset of network resources and associated policies within the underlay network. This document describes the implementation of the Operations, Administration, and Maintenance (OAM) mechanism for NRPs in Segment Routing (SR) networks. By extending existing OAM mechanisms such as ping, traceroute, Bidirectional Forwarding Detection (BFD), and Simple Two-way Active Measurement Protocol (STAMP), the proposed solution enables comprehensive NRP support in SR networks.
