Abstract:
   [RFC8287] defines the extensions to MPLS LSP Ping and Traceroute for
   Segment Routing IGP-Prefix and IGP-Adjacency Segment Identifier
   (SIDs) with an MPLS data plane.  The machinery defined in [RFC8287]
   works well in single topology, single algorithm deployments where
   each Prefix SID is only associated with a single IP prefix.  In
   multi-topology networks, or networks deploying multiple algorithms
   for the same IP Prefix, MPLS echo request needs to carry additional
   information in the Target FEC Stack sub-TLVs to properly validate IGP
   Prefix SID.

   This document updates [RFC8287] by modifying IPv4 and IPv6 IGP-Prefix
   Segment ID FEC sub-TLVs to also include algorithm identification
   while maintaining backwards compatibility.  This document also
   introduces new Target FEC Stack sub-TLVs for Prefix SID validation in
   multi-topology networks.
