ZTE ZTE [RFC8287] defines the extensions to MPLS LSP ping and traceroute for Segment Routing IGP-Prefix and IGP-Adjacency SIDs with an MPLS data plane. To correctly identify and validate an SR NRP SID, the validating device also requires NRP-ID to be supplied in the FEC Stack sub-TLV. This document introduces new Target FEC Stack sub- TLVs to perform MPLS LSP ping and traceroute for NRP SIDs.
