AS135103 ASPA Check - ALEX NEO AP Alex Neo
PublishedALEX-NEO-AS-AP Alex Neo🇸🇬 - ASPA check for AS135103: the upstream transit providers AS135103 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS135103 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 7 providers below are the only networks allowed to appear directly above AS135103 in an AS-path. If AS135103 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.
