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.
URL: <http://www.ipv6ready.org/announcement/public_review20071204_p2core.html>
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 <ipv6ready-info@ipv6ready.org>.
Personally,
I think that mandating this function is the best way.
But vendor's input will really important for them.
