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> ____________________________________________________________________

Recent changes to RPKI terms and conditions
by Karolina Bochenek 13 Oct '25

13 Oct '25

Dear all, At its 188th RIPE NCC meeting on 4-5 September 2025, the RIPE NCC Executive Board approved amendments to the RPKI (RIPE NCC Certification Service, Publish-in-Parent, Repository) Terms and Conditions. These changes are in response to the EU regulation Digital Operational Resilience Act (DORA) which came into effect in January 2025. While the requirements apply to financial institutions, the RIPE NCC aims to facilitate the implementation of this regulation for those entities that are RIPE NCC members to a reasonable extent. The following changes includes: Adding details of how we manage planned maintenance, how incidents can be reported and security measures and audits in relation to RPKI (in article 6 of Publish in Parent Service, 4 of Certification Repository and 4.3-4.7 Certification Services) Adding subcontractor, service level and data protection information (in article 8.5-8.7 of Publish in Parent Service, 6.4-6.6 Certification Repository and 7.5-7.7. Certification Services) The updates to the Terms and Conditions also include the addition of three new RPKI object types (ASPA, BGPsec and RSC) which will be implemented at a later stage. The updated RPKI terms and conditions are available at: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/legal/rip… https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/legal/rip… https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/legal/rip… The RIPE NCC Executive Board Meeting minutes are available at: https://www.ripe.net/about-us/executive-board/minutes/2025/188th-executive-… You can find more information about DORA and other relevant regulations in the RIPE NCC Trust Portal: https://trust.ripe.net/legal-compliance/ The amendment will come into effect on 13/11/2025. Kind regards, Karolina Bochenek RIPE NCC
