=> I think this might be problematic because the LL id 
is most likely different from the clobal CoA id. At least 
the MIPv6 spec specifies 3041 for CoA id generation.
So this is not a solution. 

Actually, I have the same question as Jari, why is this 
a big deal? It's not going to affect traffic to let
OptiDAD or normal DAD handle this.
