Hi Tommy and WG,

I support this work. It’s definitely useful that this draft proposes a method to apply STAMP to SR-MPLS and SRv6. It also solves the problem of round-trip path co-routing by using the Return Path TLV to determine the reverse path.

The draft has been fully discussed in WG. I think it’s ready to be adopted by WG.

This draft has been discussed and debated at length before, and the chairs would like to get input from the WG on their thoughts on this version of the document and its direction. Given the interaction with other working groups, we’d like to make progress on this in a timely fashion.

Please do send your thoughts and feedback to the list, particularly if you support this work, or if you have concerns new or existing.

   Segment Routing (SR) leverages the source routing paradigm.  SR is
   applicable to both Multiprotocol Label Switching (SR-MPLS) and IPv6
   (SRv6) data planes.  This document specifies RFC 8762 (Simple Two-Way
   Active Measurement Protocol (STAMP)) extensions for SR networks, for
   both SR-MPLS and SRv6 data planes by augmenting the optional
   extensions defined in RFC 8972.
