AS43141 ASPA Check - Swiss Innovative Arts And Technologies Institute Associazione SWISS INNOVATIVE ARTS & TECHNOLOGIES INSTITUTE (SIATI)
PublishedSwiss_Innovative_Arts_and_Technologies_Institute Associazione SWISS INNOVATIVE ARTS & TECHNOLOGIES INSTITUTE (SIATI)🇨🇭 - ASPA check for AS43141: the upstream transit providers AS43141 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS43141 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 4 providers below are the only networks allowed to appear directly above AS43141 in an AS-path. If AS43141 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.
