   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 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 networks in an efficient
   manner with simple OAM protocol extension which uses dataplane
   forwarding alone for sending Echo-Reply.
