    Reviewer: Nagendra Nainar
    Review result: Has Issues

    Hi,

    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 per guidelines in RFC5706.

    Comments that are not addressed in 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.

    Overall Summary:

    This draft is attempting to summarize the problems related to the current
    practice for extending DHCPv6 protocol. This document does not propose any
    solution, framework, or protocol extensions and so it does not raise any
    backward compatibility challenges or operational considerations.

    While the document does not raise any operational/management considerations, I
    am choosing "Has Issues" as the overall draft may need substantial changes.

    Few comments below:

     The manageability, security, privacy protection, and traceability of
       networks can be supported by extending the DHCPv6 protocol according
       to requirements.  This document provides current extension practices
       and typical DHCPv6 server softwares on extensions, defines a DHCPv6
       general model, discusses some extension points, and presents
       extension cases.

    --> The abstract is not clear in reflecting what the draft is about. Based on
    the above, this draft appears to be discussing current extension practice,
    extension points, and cases which is more like a survey document that
    summarizes what we have currently. This being a draft that attempts to document
    the problem statement, it will be good to reflect the same in the abstract.

    --> The Introduction section may need some rework. It is not clear in defining
    what is multi-requirement extension problem.

    --> I think, a section (or sub-section) clarifying what is multi-requirement
    extension with an example use case will help the readers to better understand
    the objective of this document.

    Regards,
    Nagendra
