Technical Summary

   The Segment Routing (SR) architecture leverages source routing and
   can be directly applied to the use of a MPLS data plane.  An SR-MPLS
   network may consist of multiple IGP domains or multiple Autonomous
   Systems(ASes) under the control of the same organization.  It is
   useful to have the Label Switched Path (LSP) ping and traceroute
   procedures when an SR end-to-end path traverses multiple ASes or
   domains.  This document describes mechanisms to facilitate LSP ping
   and traceroute in inter-AS and inter-domain SR-MPLS networks in an
   efficient manner with a simple Operations, Administration and
   Maintenance (OAM) protocol extension which uses data plane forwarding
   alone for forwarding echo replies on transit nodes.

Working Group Summary

   As highlighted in the document shepherd report there was little discussion on this document but it was reviewed by several key participants of the WG and rough consensus was reached to move the document forward. 

Document Quality

   As highlighted in the shepherd report there is an RFC 7942 Implementation Status section as Section 12 of the document. It describes a single vendor's prototype implementation.

Personnel

   The Document Shepherd for this document is Adrian Farrel. The
   Responsible Area Director is Jim Guichard.
