   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.  RFC8287 proposes 3 Target FEC Stack
   Sub-TLVs.  While the standard defines the format and procedure to
   handle those Sub-TLVs, it does not sufficiently clarify how the
   length of the Segment ID Sub-TLVs should be computed to include in
   the Length field of the Sub-TLVs which may result in interoperability

   This document updates RFC8287 by clarifying the length of each
   Segment ID Sub-TLVs defined in RFC8287.
