AS3445 ASPA Check - ESnet
PublishedESNET-AS - ESnet๐บ๐ธ - ASPA check for AS3445: the upstream transit providers AS3445 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS3445 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The provider below is the only network allowed to appear directly above AS3445 in an AS-path. If AS3445 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.
