RFC 9994: MPLS Network Action (MNA) Sub-Stack Specification Including In-Stack Network Actions and Data

In plain English — editorial summary, not part of the RFC

This document specifies the MPLS Network Action (MNA) Sub-Stack for carrying network actions and Ancillary Data (AD) in the MPLS label stack. MNA can be used to influence packet-forwarding decisions, carry additional Operations, Administration, and Maintenance (OAM) information in the MPLS packet, or perform user-defined operations. This document updates RFC 9789 to refine the list of pieces of information that must be included in any document that defines an MNA.
