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. Distribution of this
memo is unlimited.
