Hello Subrata,

I reckon I am missing your point, so here is a request for clarification:

The choice seems to be to do DAD once for a "link-local" or
"subnet-local" address (even if the node didn't configure one (?!?)),
vs. doing DAD for _every_ configured address.

So, the thing you label a "restriction" seems to bring a large
measure of freedom, if I understand you correctly.

The HA would deny that node use of the link.  This is quite unlikely
to ever happen, though.

I don't understand what you mean here.  Which addresses are useless?
