[support] Why does HA do ndisc_do_dad action?

[tony chen]

Hi everybody, I have a problem about DAD at HA.
When I go to the foreign network from home network,
I can find the DAD success message from the HA debug message.

I feel confusing, why does the ha do the DAD action,
for what ??

Thank everybody replying me or viewing the text.
