PublishedTSPU-AS State educational institution of higher professional education "Tomsk State Pedagogical University"🇷🇺 - ASPA check for AS50433: the upstream transit providers AS50433 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS50433 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 6 providers below are the only networks allowed to appear directly above AS50433 in an AS-path. If AS50433 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.
