What doesn't work in this case?? I don't understand what you're saying.

That much is obvious.

Allowing all possible /48s out of all PA /32s and bigger just because  
the /32 might be down is a very bad idea because not only are you  
allowing unaggregatable PI (which is already very bad), but you're  
also setting yourself up for very big problems when people accidently  
deaggregate.

Right.

Anyone in Sweden for the big fight?
