ripe is being overgenerous to the swiss!
Not so. They are pretending to be over-endowed to some peers only.
Not so, as has been re-re-re-hashed, 3303 is sending bogon feeds to some parties [presumably their customers] and those are getting regurgitated to route-views. route-views is a varied slice of different kinds of announcement sets (full tables, partial, internal deaggs, ect etc); looking-glass comparison shopping is the only way to get meaningful data.
the problem is that those getting the over-reaching data have a view of the internet which can cause them and some destinations problems. this is very analogous to seeing 0/0 with a six hop path in route-views, as you say, we don't really know the reach of the bad data. randy
