No, it hits 30% of the *routes*. I'll make a truly wild guess and say that those 30% of routes actually only represent 0.3% of the *traffic* for most providers, and the *only* people who really care are the AS that's doing the deaggregate... Eduardo - if you still have the lab setup and netflow/whatever data, is there any way to tell if any of those 30% routes affected are in any way "high traffic" sites?
