Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this
Internet-Draft. The scope of the document is clear and it is almost ready. It
defines the BIER OAM packet format and the related mechanisms.

- Document: draft-ietf-bier-ping

- Reviewer: Will LIU

- Review Date: 12/11/2025

## Summary

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

---

I have few comments:

- In section 3.1, it is mentioned that Hybrid OAM can also be used. I suggest
to clarify this point. Maybe, it can be highlighted in the introduction and
explain which OAM methods (Active, Hybrid, Passive) can be enabled with BIER
OAM.

- I would define the BIER Echo Request/Reply message format in a separate
section to improve readability. Maybe a subsection of section 3.1 could be ok.

- Section 4 covers ping and traceroute operations. Therefore, I suggest to be
more specific and revise the title of the section accordingly.
