A new Request for Comments is now available in online RFC libraries. RFC 8690 Title: Clarification of Segment ID Sub-TLV Length for RFC 8287 Author: N. Nainar, C. Pignataro, F. Iqbal, A. Vainshtein Status: Standards Track Stream: IETF Date: December 2019 Mailbox: naikumar@cisco.com, cpignata@cisco.com, faisal.ietf@gmail.com, vainshtein.alex@gmail.com Pages: 7 Updates: RFC 8287 I-D Tag: draft-ietf-mpls-rfc8287-len-clarification-04.txt URL: https://www.rfc-editor.org/info/rfc8690 DOI: 10.17487/RFC8690 RFC 8287 defines the extensions to perform LSP Ping and Traceroute for Segment Routing IGP-Prefix and IGP-Adjacency Segment Identifiers (SIDs) with the MPLS data plane. RFC 8287 proposes three Target Forwarding Equivalence Class (FEC) Stack sub-TLVs. While RFC 8287 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 be included in the Length field of the sub-TLVs. This ambiguity has resulted in interoperability issues. This document updates RFC 8287 by clarifying the length of each of the Segment ID sub-TLVs defined in RFC 8287. This document is a product of the Multiprotocol Label Switching Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
