Are 0.0.0.0/0 routes filtered by RIPEstat but included in RIS dumps? Should rpki-validator filter them out?
In the bgp-preview? Probably. Although the route is in RIS, provided by some peers, 0.0.0.0/0 does more harm than good in tools like RIPEstat and the rpki-validator's preview. Alternatively, developers could raise the lower limit of number of RIS peers which must see a route before it is included in the preview. Currently, that limit is set to 5. The 0.0.0.0/0 routes typically have very low visibility. The latest dump at http://ris.ripe.net/dumps/riswhoisdump.IPv4.gz sees 0/0 announced by 24 different ASes. But where most of them are seen by just 1, 2 or 3 out of 222 full feed RIS peers, the announcement by AS15576 is seen by 5 peers and thus makes it to the preview. -- Rene
