In DNAv4 we said that if the alternative method (in that case, DHCP) arrived first, we would stop retransmitting probes (and presumably ignore probe responses). I'd say the same thing about DHCPv6, by the way. If the DHCPv6 response comes back before a probe response, then just configure the address and stop the probes. |
