Hi Dave,

What's being proposed is an optimization. If the router does not understand the request, or does not want to process such messages, then DAD continues as normal. Since the nodes are forced to perform MLD for the solicited-node address, the issue of whether the Querier Router actually keeps state is implementation dependent, IMHO. > Furthermore, there is a proposal under discussion to > not do DAD, except on manually assigned addresses. > If this proposal is accepted, there's little benefit to > trying to optimize DAD any further (certainly not worth > asking routers to start keeping extra state). Until there's consensus in the WG, I suggest that there's a great deal of benefit in assessing ways to remove the delay issues in DAD, without killing it. I'll send out the draft soon so you can have a look at it before you make a final decision ;-) Greg Daley -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
