The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'RFC8287 Sub-TLV Length Clarification' <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 ietf@ietf.org mailing lists by 2019-07-31. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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. 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 issues. This document updates RFC8287 by clarifying the length of each Segment ID Sub-TLVs defined in RFC8287. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-mpls-rfc8287-len-clarification/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-mpls-rfc8287-len-clarification/ballot/ No IPR declarations have been submitted directly on this I-D.
