I was at the meeting. I did not hear consensus for this at all or in mail follow up or at Atlanta. I don't believe all agree with this view at all and I know all the users don't and all the vendors don't and all on this list. So what do you mean by all? > > This is properly reflected in section 5.3 (nodes MAY support > DHCPv6), in section 4.5.2 (MUST support stateless) and in the > current text of section 4.5.5, which is just fine. The reason I did not object to that is because DHCPv6 had not reached proposed standard I will have to think if I object to that now that you bring it up. But DHCPv6 is just one method of Statefull we know today, and probably should be a MAY but now will think on that too. So the two references are orthognal. Besides M there is O bit. That means use statefull for other configuration and that is another issue. The implementation of M and O bit should be a SHOULD. I do not believe we have consensus on the view you state above. Nor do I believe that all discussion points have been brought forth for such an important decision.
