AS18024 ASPA Check - Bhutan Telecom
PublishedBTTELECOM-AS-AP - Bhutan Telecom Ltd🇧🇹 - ASPA check for AS18024: the upstream transit providers AS18024 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS18024 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 AS18024 in an AS-path. If AS18024 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.
