Phenomenon:

ifconfig: Duplicate address detected on link hme1 for address fec0:1380::100. Code 1

If an IPv6 address is overlapping with the other systems, when attempting to activate an interface, the address overlap detection function causes to stop the activation of a take over IP address. Be sure to check the other systems for over lapping IP addresses.
