   A Segment Routing architecture leverages source routing and tunneling
   paradigms and can be directly applied to use of a Multi Protocol
   Label Switching (MPLS) data plane.  A node steers a packet through a
   controlled set of instructions called segments, by prepending the
   packet with a Segment Routing header.

   The segment assignment and forwarding semantic nature of Segment
   Routing raises additional consideration for connectivity verification
   and fault isolation for an LSP within a Segment Routing architecture.
   This document illustrates the problem and defines extensions to
   perform LSP Ping and Traceroute for Segment Routing IGP Prefix and
   Adjacency SIDs with an MPLS data plane.
