The process to create a ROA through each RIR portal
by Sofia Silva Berenguer 03 Oct '25

03 Oct '25

(Apologies for duplicates) Hi all, The NRO has just published a new reference page: https://www.nro.net/technical-coordination/nro-rpki-program/joint-rpki-base… This page brings together direct links to each RIR’s official documentation for creating Route Origin Authorisations (ROAs) through their portals and summarises some differences across the RIRs. Why this matters: * This page gives operators a single place to find the correct entry point, no matter which RIR(s) you hold resources with. * It also helps compare the different processes across RIRs without having to search separately. The aim is to keep the RIR websites as the source of truth while providing a convenient overview in one place. A FAQ page is also available: https://www.nro.net/technical-coordination/nro-rpki-program/joint-rpki-base… If you have any questions or comments, please reach out to us at rpki_program(a)nro.net We hope you’ll find this a helpful resource. Warm regards, Sofía -- I am sending this email at a time that suits me and the time zone I work in. Please feel free to read, and act on or respond, at a time that suits you. ____________________________________________________________________ Sofía Silva Berenguer NRO RPKI Program Manager e: sofia(a)apnic.net<mailto:sofia@apnic.net> ____________________________________________________________________

2025-02 Last Call for Comments (Revocation of Persistently Non-functional Delegated RPKI CAs)
by Angela Dall'Ara 10 Sep '25

10 Sep '25

Dear colleagues, Proposal 2025-02, "Revocation of Persistently Non-functional Delegated RPKI CAs" is now in Concluding Phase. This proposal suggests providing a mandate to the RIPE NCC to revoke resource certificates associated with longtime non-functional CAs to reduce Relying Party workloads. The WG co-chairs have declared that rough consensus has been reached and the proposal will now move to Last Call. As per the RIPE Policy Development Process (PDP), the purpose of this four-week Concluding Phase is to give an opportunity to present well-justified objections for those who missed the previous two phases and wish to oppose the proposal. Any objection must be made before 9 October 2025 and must be supported by an explanation. If no substantive objections are raised by the end of Last Call, the proposal will complete the PDP and will be evaluated by the WG co-chairs for final consensus. You can find the full proposal at: https://www.ripe.net/community/policies/proposals/2025-02/ Please e-mail any final comments about this proposal to routing-wg(a)ripe.net before 9 October 2025. Kind regards, Angela Dall'Ara Policy Officer RIPE NCC

2025-02 End of Review Phase (Revocation of Persistently Non-functional Delegated RPKI CAs)
by Sebastian Becker 10 Sep '25

10 Sep '25

Dear Routing WG, The review phase for proposal 2025-02: "Revocation of Persistently Non-functional Delegated RPKI CAs" ended on 5 September. Thanks to everyone that participated in the discussion. Ten people fully supported the proposal: Max Emig Theo Buehler Ben Cartwright-Cox Niels Raider Filip Hruska Gert Doering Tobias Fiebig Radu Anghel Simon Leinen Lukas Tribus No objections were raised. Additional comments: Tim Bruijnzeels agreed with Theo Buehler's suggestion to clarify, in the wording of the first paragraph of the impact Analysis, that the period triggering a non-functional CA revocation would start from the nextUpdate timestamp expiry. Job Snijder agreed with the RIPE NCC understanding of his proposal. Based on the feedback received from the Working Group, we declare that rough consensus has been achieved for this proposal and ask RIPE NCC Policy Officer to follow up announcing the start of the Concluding Phase (Last call). Kind regards, Sebastian Becker, for the Routing WG Chairs

If you see anything missing, unclear, or that needs an update, please send your input to rpki_program(a)nro.net Thanks in advance for helping us make this a stronger resource for the community! Warm regards, Sofía -- I am sending this email at a time that suits me and the time zone I work in. Please feel free to read, and act on or respond, at a time that suits you. ____________________________________________________________________ Sofía Silva Berenguer NRO RPKI Program Manager e: sofia(a)apnic.net<mailto:sofia@apnic.net> ____________________________________________________________________
