Dear colleagues, We enabled ASPA support in the RIPE NCC RPKI Dashboard on 26 November. An ASPA object is a signed RPKI Object that allows the holder of an AS number to authorise one or more other AS numbers to appear as their legitimate upstream providers in BGP. ASPA validation can help to prevent BGP route leaks, and to a degree improves BGP path security. While the IETF standards have not yet reached RFC status, the discussions have been resolved. We therefore consider ASPA signing ready for use. But, before you start we recommend that you read the documentation here: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/aspa/ Or watch the RIPE 91 presentation on ASPA in the RPKI Dashboard: https://ripe91.ripe.net/programme/meeting-plan/sessions/30/VZNKWV/ Please let us know if you have any questions or comments. Kind regards, Tim Bruijnzeels Principal Engineer RPKI RIPE NCC
