Re: [MBONED] Benjamin Kaduk's Discuss on draft-ietf-mboned-ieee802-mcast-problems-14: (with DISCUSS and COMMENT)

[- IESG to save bandwidth]

Dear authors,

As the responsible AD for this document (as Warren Kumari is an author), I am quite happy to see that Ben Kaduk's original DISCUSS has been cleared.

The new one is correct and seems easy to address but following his suggestion of using the obsoleted reference.

The same for Ben's 2 COMMENTS: ARP fix appears to be obvious and, while I am ambivalent about his 2nd non-blocking comment, it can be addressed by removing " including options for when traffic should be sent wired".

It is obviously up to the authors to address the above. Next week, the upload of a revised I-D is open again and then I could approve the I-D for publication ;-)

Regards

-éric

    DISCUSS:
    ----------------------------------------------------------------------

    Many thanks for all the updates from -11 to -14; the preponderance are
    good and improve the document.

    I especially appreciate the change in section 9 to claim only that the
    use of IPsec is specified, rather than mandated, by the referenced
    document.  Unfortunately, the reference document was changed as well,
    from RFC 4601 to RFC 7761, but RFC 7761 calls out as one of the changes
    from RFC 4601 that "authentication using IPsec" was removed.  So the
    current claim in the -14, that "[RFC7761] [...] specifies the use of
    IPsec to ensure authentication of the link-local messages in [PIM-SM]"
    is not correct, though for a different reason than what I noted in my
    ballot position on the -11.  It may be most expedient to just restore
    the reference to the obsolete document, though of course there are other
    possibilities.

    COMMENT:

    Section 3.2.1

       o  ARP [RFC5424]

    RFC 5424 is "The Syslog Protocol"; while RFC 5494 is only hamming
    distance one away and relates to ARP, it seems that the original RFC 826
    might actually be a better reference.

    Section 8

    I'm still a little confused by the first point -- it seems to be
    suggesting that some types of multicast traffic might only be sent if
    sending over a wired interface and just dropped for wireless interfaces,
    which both introduces a layering violation and causes wireless to be a
    "second-class citizen".  Presumably there is some more subtlety than
    that, but I'm missing it.
