AS212783 ASPA Check - FR FEREZ Gaetan Ferez
PublishedFR-FEREZ-AS Gaetan Ferez🇫🇷 - ASPA check for AS212783: the upstream transit providers AS212783 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS212783 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 5 providers below are the only networks allowed to appear directly above AS212783 in an AS-path. If AS212783 uses a transit provider that is missing from this list, routers that enforce ASPA treat its routes through that provider as invalid, so the list should include every current and backup transit provider. Peers do not belong in it.
