AS20738 ASPA Check - GD EMEA DC LD5 Heart Internet Limited
PublishedGD-EMEA-DC-LD5 Heart Internet limited🇬🇧 - ASPA check for AS20738: the upstream transit providers AS20738 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS20738 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 AS20738 in an AS-path. If AS20738 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.
