AS49935 ASPA Check - SmartEye B.V
PublishedSmartEye SmartEye B.V🇧🇪 - ASPA check for AS49935: the upstream transit providers AS49935 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS49935 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 66 providers below are the only networks allowed to appear directly above AS49935 in an AS-path. If AS49935 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.
Step-by-step ASPA check guide - including how to validate an AS-path hop by hop.
