# OPSDIR review of draft-ietf-roll-dao-projection

I have reviewed this document as part of the Operational directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written with the intent of improving the operational aspects of
the IETF drafts. Comments that are not addressed in the last call may be
included in AD reviews during the IESG review.  Document editors and WG chairs
should treat these comments just like any other last-call comments.

This document extends RFC 6550, RFC 6553, and RFC 8138, introducing the DAO
Projection
 mechanism to enhance RPL. It enables the RPL root or an external controller to
 proactively install optimized routes, improving routing efficiency,
 reliability, and resource utilization. Additionally, the draft addresses
 backward compatibility, all nodes involved in P-DAO processing must support
 this specification. The document is clear and well-written. The motivation is
 described well. The document is almost ready for publication.
