RIPE IRR DB schema changes (follow-up from Q at mic)
by Job Snijders 25 Oct '17

25 Oct '17

Dear Ruediger, routing-wg, Today at the microphone Ruediger asked "Where can I read the solution?". The procedure to move work through db-wg is described here: https://www.ripe.net/manage-ips-and-asns/db/numbered-work-items We are now in "phase 2", which states: "For the NWI to move to Phase 3, the RIPE NCC has to provide the working group with a summary of their understanding of the solution, and the chairs declare consensus on the group's acceptance of this summary." The summary of RIPE NCC's understanding (who are the people supposed to implement the request) will probably be the closest thing to a formal description of what the proposed change entails. RIPE NCC was tasked to do their part through this email https://www.ripe.net/ripe/mail/archives/db-wg/2017-October/005711.html So, we are now waiting for RIPE NCC's feedback. This step serves to ensure that the NCC's understanding and the working group's understanding actually are aligned. Kind regards, Job ps. I'll try to summarize the 2 changes for the benefit of the working group. There has been extensive discussion on _why_ these two changes are deemed helpful, that discussion can be read here: https://www.ripe.net/ripe/mail/archives/db-wg/2017-October/thread.html 1) To put the "removal of origin authorization" in context of RPSS. Section 6 (https://tools.ietf.org/html/rfc2725#section-6) states: "The key attributes in a route object (key with regard to making it unique) contain both an address prefix and an AS number, known as the origin AS. The addition of a route object must be validated against the authorization criteria for both the AS and the address prefix." Essentially that aspect is changed to: "The key attributes in a route object (key with regard to making it unique) contain both an address prefix and an AS number, known as the origin AS. The addition of a route object must be validated against the authorization criteria for the address prefix." 2) Furthermore, if the route/route6 object falls outside the address space pool that RIPE NCC manages, instead of "source: RIPE", "source: RIPE-NONAUTH" is used to signify that the RIPE IRR is not an authoritative source for information about that address prefix.

New on RIPE Labs: Power Prefixes Prioritisation for Smarter BGP Reconvergence
by JUAN BRENES BARANZANO 24 Oct '17

Dear Olivier and Job, Thanks for your feedback, and sorry for delayed answer (I thought I was already subscribed to the mailing list, but I was not). I was sure the question about PIC and ADD-PATH was going to appear, and I am going to address it in the presentation. The answer is that we mainly target scenarios where you can't use PiC either because the operator is using next hop self (which we understand is fairly common) or because there is no IGP to update the pointer. Going back to Job's questions: 1) Would it perhaps make sense to rank updates by BGP next-hop (using a metric like traffic volume), rather than destination prefixes themselves? Each BGP next-hop in effect represents a group of prefixes. We are not pushing any ranking algorithm. We used the traffic because it was the most relevant concern at that moment, but we can also consider other algorithms. For instance, we received a comment about considering critical services like the DNSs at the top of the list. For sure I agree we can consider ranking traffic by next hop, but as we are mainly targeting the next hop self situation this can be tricky. 3) Are you looking to publish your work in context of IETF or IRTF? We are still to decide how and where to present this. IETF is definitely one option. Any suggestions about how to go about resenting this in the IETF? do you suggest to just have an informative presentation in something like GROW WG or do you think it would make sense to write a draft describing the mechanism and see if any WG is willing to take this on?

New on RIPE Labs: Power Prefixes Prioritisation for Smarter BGP Reconvergence
by Mirjam Kuehne 22 Oct '17

22 Oct '17

Dear colleagues, Please find this new article on RIPE Labs by Juan Brenes, one of the RACI fellows at RIPE 75: Power Prefixes Prioritisation for Smarter BGP Reconvergence Every day the Internet experiences failures that affect the reachability of certain zones (i.e prefixes), such as cities, countries, etc. Whenever such events happen, the routing information, which is the path that information must follow in order to get from one place to another, must be updated so that the failure is circumvented and the zone becomes reachable again. https://labs.ripe.net/Members/juan_brenes/power-prefixes-prioritisation-for… Juan will present this topic at the Routing WG session later this week. Kind regards, Mirjam Kuhne RIPE NCC
