Technical Summary

This document defines the MPLS Network Actions (MNA) sub-stack
solution for carrying Network Actions and Ancillary Data in the MPLS
label stack. MNA can be used to influence packet forwarding
decisions, carry additional Operations, Administration, and
Maintenance information in the MPLS packet or perform user-defined
operations. The solution specified in this document addresses the
requirements for In-stack network action and In-stack data found in
RFC 9613. This document follows the architectural framework for the
MNA technologies specified in RFC 9789.

Working Group Summary

Broad concensus to move forward to publication. Many directore reviews and 3 WG LCs have significantly improved the document.

Document Quality

As per the shepherd writeup, the document includes an implementation section in Section 12. There is one reported implementation of the solution.

Personnel

The Document Shepherd for this document is Tarek Saad. The Responsible
Area Director is Jim Guichard.
