Hi, http://www.ietf.org/internet-drafts/draft-ietf-6lowpan-nd-13.txt
We submitted an updated version of ND. This now includes a solution for the duplicate MAC address issue using a simple Error-to feature (See Section 6.5.2 "Returning Address Registration Errors"), along with new examples contributed by Colin (thanks!) and editorial comments from Carsten. The only change this draft affects for -12 implementations is the destination address used for returning NA messages with an ARO error (Status > 0).
