That's what I'm curious about...this boils down to L3 not properly 
filtering Hanaro.

Having recently turned up some L3 connectivity, I was happy to discover 
that they can use any of the routing registries as the source of their 
prefix filters. They told me the prefix filters are automatically 
constructed based on the RR of your choice...update the RR, and their 
filters will update that night, no need to bug them. Yay for that, wish 
everybody worked that way.

But...why wasn't Hanaro being filtered? If the filters are being 
automatically generated, I would think they would just filter all of their 
peers regardless of number of prefixes etc.
