The IESG has received a request from the Multiprotocol Label Switching WG
(mpls) to consider the following document: - 'RFC8287 Sub-TLV Length
  <draft-ietf-mpls-rfc8287-len-clarification-02.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the mailing lists by 2019-07-31. Exceptionally, comments may be
sent to instead. In either case, please retain the beginning of
the Subject line to allow automated sorting.


   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.
