IPv6 Duplicate address found - NA reponse
If an NS is sent and a host on the link finds it is using the tentative IPv6 address described in the NS, it responds with an NA. Doyle's TCP/IP Routing Vol. 1 states that "If a node receives an NS and the target address matches one of its assigned addresses, it sends an NA with the Target Address and the destination address set to the tentative address."The first host has used a source address of ::/128 so if the NA sets the destination address as the tentative address, how does it reach the first device (the one who sent the NS for DAD)?
