AS401664 ASPA Check - COMMUNICATION CHARLEVOIX RIVE NORD (CCRN)
PublishedINTERNET-CCRN-01 - COMMUNICATION CHARLEVOIX RIVE-NORD (CCRN) INC🇨🇦 - ASPA check for AS401664: the upstream transit providers AS401664 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS401664 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 AS401664 in an AS-path. If AS401664 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.
