Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this
Internet-Draft.

The Operational Directorate reviews all operational and management-related
Internet-Drafts to ensure alignment with operational best practices and that
adequate operational considerations are covered.

A complete set of _"Guidelines for Considering Operations and Management in
IETF Specifications"_ can be found at
https://datatracker.ietf.org/doc/draft-ietf-opsawg-rfc5706bis/.

While these comments are primarily for the Operations and Management Area
Directors (Ops ADs), the authors should consider them alongside other feedback
received.

- Document: draft-ietf-idr-flowspec-redirect-ip-06

- Reviewer: Linda Dunbar

- Review Date: April 13, 2026

- Intended Status: Standards Track

---

## Summary

- Has Nits: This document is basically ready for publication but has nits that
should be considered prior to publication.

## General Operational Comments Alignment with RFC 5706bis

I do not see any major architectural problem with the document.

## Major Issues

 No major issues found.

---

## Minor Issues

  It would be helpful to provide a bit more guidance on observability and
  troubleshooting when redirect-to-IP is ignored due to validation failure,
  unreachable target address, or interaction with other FlowSpec actions

---

## Nits

- Section 3 last sentence: “section Section 2.1” should be fixed.

- Section 4: the word "documentations" should be changed to "documents"?
This section documentations the [RFC7942] implementation status...” should be
fixed

- Section 4.4: Typo: “IWidely Used”  .

Best Regards,
Linda Dunbar
