Reading the section you reference, we do follow all the MUST requirements, and
we log an error.  Given that the disable section is a SHOULD, I think we can at
least be somewhat more restrictive in our implementation.  Perhaps we should
just disable the interface iff the failed address is link-local AND there are no
other functional address assigned to the interface.

I agree here, but it seems that currently the IPv6 Logo Committee thinks
that it has to be disable the interface to get the IPv6 ready Logo in
future. I already claim that on a discussion at the TAHI users list.

JFYI, here the answer from the TAHI list.

    Hi, Karsten.

    Thanks for your comments.

    I know that it is SHOULD,
    but our test tool supports the test specification
    published by IPv6 Ready Logo Program <http://www.ipv6ready.org/>,
    and basically the test specification supports all of MUST and SHOULD.

    You may know,
    now IPv6 Ready Logo Committee is also discussing
    about the next major revision up of test specification.


    RFC 4862 Section 5.4.5 is one of discussing point.

    The public review has been over,
    but if you have strong concern about it,
    I recommend to comment to [off-list ref].

    Personally,
    I think that mandating this function is the best way.
    But vendor's input will really important for them.

So it would be good if some of the networking experts complain there.
