If you're using a default route to overcome a limited FIB, you want a more reliably chosen set of routes to filter than the stray error route that shouldn't have reached you. Nearly all paths on the Internet are still under 64 hops wide (packet TTL of 64) so finding a non-customer route with more than double that number of elements in the AS path suggests someone tried to do something fancy in a local environment and it leaked. Not only is it reasonably safe to discard such routes, long AS paths have been responsible for triggering bugs in multiple BGP implementations. Failing to filter it may actually be harmful to folks downstream from you. Regards, Bill Herrin -- For hire. https://bill.herrin.us/resume/

The FIB is where the 'winning' prefixes go as fully-resolved things from the RIB, but the RIB too would not have it, as an alternative won in BGP. And even if you depref'd it in BGP, it would still be there in the control-plane, consuming the same amount of RAM. Reject it for excess prepends is likely the best choice.

AS701 anycasts any IP?
Hi, while investigating an issue I was wondering a german IP was only 1-2 hops away from some RIPE Atlas Probes connected via AS701. It seems at least probe #50235 and #54508 see any IP directly as next hop, as an example here with the IP of mailop.org: https://atlas.ripe.net/measurements/44133927/ Regards Bjoern
