>Since NS(DAD) traverse the same link, couldn't we just use src MAC of the received NS(DAD) to identify if the NS is the one sent by the interface earlier? No. Two nodes could almost simultaneously issue a NS(DAD) and both the nodes have the same mac-address and thus the situation is a DAD failure and not a looped back NS(DAD). I use the term of NS(DAD) to denote a NS issue for the purpose of DAD where the NS has a unspecified source address. That is why a nonce is needed and specified in a completed algorithm to detect looped back NS(DAD) messages in http://tools.ietf.org/html/draft-hsingh-6man-enhanced-dad-01 Hemant -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
