ASPA support added to the RIPE NCC RPKI Dashboard
by Tim Bruijnzeels 03 Dec '25

03 Dec '25

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

bgp origin attribute
by Alexander Zubkov 31 Oct '25

31 Oct '25

Hi James and all, James, thanks for raising up this topic with BGP Origin attribute. Have you thought already about making an RFC draft to not consider Origin attribute in the BGP decision process? It seems to be a reasonable next step. PS. And maybe Router ID as well. :) Regards, Alexander Zubkov Qrator Labs

Discussion: Draft on RPKI Trust Anchor Constraints in SIDROPS
by Sofia Silva Berenguer 30 Oct '25

30 Oct '25

(Apologies for duplication) Hello all, The NRO RPKI Program [1] has published a blog post explaining the proposed solution to concerns with the current RPKI Trust Anchor configuration, now documented in the Internet-Draft https://www.ietf.org/archive/id/draft-nro-sidrops-ta-constraints-00.txt The draft defines a mechanism that allows RPKI Trust Anchors (TAs) to declare which TA is authoritative for which Internet Number Resources, helping prevent RPKI validation conflicts. You can read the blog post here: https://labs.ripe.net/author/sofia_silva_berenguer/a-solution-to-concerns-o… We welcome feedback and discussion on the sidrops mailing list [2] and during the upcoming SIDROPS WG session at IETF 124 (Montreal, Nov 3) [3]. Warm regards, Sofía — [1] https://www.nro.net/technical-coordination/nro-rpki-program/ [2] https://mailman3.ietf.org/mailman3/lists/sidrops@ietf.org/ [3] https://datatracker.ietf.org/meeting/124/session/sidrops ____________________________________________________________________ Sofía Silva Berenguer NRO RPKI Program Manager e: sofia(a)apnic.net<mailto:sofia@apnic.net> ____________________________________________________________________
