RFC 9489: Label Switched Path (LSP) Ping Mechanisms for EVPN and Provider Backbone Bridging EVPN (PBB-EVPN)

Label Switched Path (LSP) Ping is a widely deployed Operations, Administration, and Maintenance (OAM) mechanism in MPLS networks. This document describes mechanisms for detecting data plane failures using LSP Ping in MPLS-based Ethernet VPN (EVPN) and Provider Backbone Bridging EVPN (PBB-EVPN) networks.
