Hi Suresh, Thank you for your comment.
But Windows Vista and 7 are correctly updating preferred lifetime. :-) (i.e. It conforms to Section 5.5.3 of RFC4862.) The problem is that Windows Vista and 7 don't restore to "Preferred" from "Deprecated". Please see my question. >Can IPv6 address restore to Preferred State from Deprecated state? >I think it's possible to do. However, there is no clear description > in RFC4861/4862. Is it written in other RFCs? We have to define clearly in RFC?
