Abstract:
   Segment Routing (SR) architecture leverages source routing and
   tunneling paradigms and can be directly applied to the use of a
   Multiprotocol Label Switching (MPLS) data plane.  A network may
   consist of multiple IGP domains or multiple ASes under the control of
   same organization.  It is useful to have the Label switched Path
   (LSP) Ping and traceroute procedures when an SR end-to-end path spans
   across multiple ASes or domains.  This document describes mechanisms
   to facilitae LSP ping and traceroute in inter-AS/inter-domain SR-MPLS
   networks in an efficient manner with simple Operations,
   Administration, and Maintenance (OAM) protocol extension which uses
   dataplane forwarding alone for sending echo reply.
