Technical Summary
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. RFC 8287 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.
Working Group Summary
There were no controversies progressing this document, the support
in the working group is solid.
Document Quality
In this case the question of existing implementations is a bit
tricky, the document is a clarification to RFC 8287, of which there
are implementations. The problem with the Segment ID Sub-TLV was
discovered when preparing inter-op test of RFC 8287.
