AS11752 ASPA Check - Nucleo De Inf. E Coord. Do Ponto BR NIC.BR
PublishedAS11752 - Nucleo de Inf. e Coord. do Ponto BR - NIC.BRš§š· - ASPA check for AS11752: the upstream transit providers AS11752 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS11752 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 AS11752 in an AS-path. If AS11752 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.
