I disagree. I think the problem is in the RFC 2462 optimization. The RFC 2462 optimization also can fail with manually-configured addresses - it's not just a problem with RFC 3041 temporary addresses.
I'm curious about the implementation status. I know the Windows implementation does not implement the RFC 2462 optimization - it performs DAD on every address independently. What about other implementations? Rich > -----Original Message----- > From: Charles E.
