Comments 
This document is intended to take RFC7348 (VXLAN), which was originally published through the Independent Submission Editor, into the IETF stream, allowing the IETF to create a registry to make use of unused bits in the VXLAN header for new applications. VXLAN is very widely deployed and it is important not to impact those existing deployments. Please review from the perspective of the clarity of the specification, or any technical issues with the extensions/changes with respect to RFC7438.

This is a Routing Directorate (early) review as requested.
Draft: draft-ietf-nvo3-rfc7348bis-02
Reviewer: Joel M. Halpern
Review Date: 12-Nov-2025

Summary: Ready, with one major but easily addressed concern

Major:
    I can not find any text describing whether there is any difference in the
    packet format or packet processing rules between this document and RFC7348.
     My guess is that there is no difference, and this document should say that
    (e.g. it could say "The format and processing described here are fully
    compatible with those in RFC 7348.)  If there are changes, those should be
    described.

Minor: N/A
