AS210132 ASPA Check - THOMAS GLANZMANN Thomas Glanzmann
PublishedTHOMAS-GLANZMANN Thomas Glanzmann🇩🇪 - ASPA check for AS210132: the upstream transit providers AS210132 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS210132 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 AS210132 in an AS-path. If AS210132 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.
