aggregate6 - a fast versatile prefix list compressor
by Job Snijders 30 Nov '17

30 Nov '17

Dear routing-wg, I re-implemented the venerable 'aggregate' tool (by Joe Abley & co) in python under the name of 'aggregate6'. The 'aggregate6' tool is faster and also has IPv6 support. https://github.com/job/aggregate6 Installation is can be done through 'pip', or your operating system's package manager (if they carry the 'aggregate6' tool). $ pip install aggregate6 Example use: $ echo 10.0.0.0/16 10.0.0.0/24 2000::/4 3000::/4 | aggregate6 10.0.0.0/16 2000::/3 Note that 'aggregate6' can also be imported as module in your own python project: >>> import from aggregate6 import aggregate >>> aggregate(["10.0.0.0/8", "10.0.0.0/24"]) ['10.0.0.0/8'] >>> Related to the above example, NTT uses 'aggregate6' as library in their network automation toolchain to help compress firewall rules. When using a dump from the IPv4 Default-Free Zone, it appears that 'aggregate6' can deaggregate that list ~ 50 times faster than 'aggregate'. However the tradeoff is that 'aggregate6' uses a bit more memory. Aggregate6 has been tested with pypy, python2 and python3; and can be used both from the command line and as python module. Aggregate6 is published under the 2-Clause BSD license. Kind regards, Job

DB WG NWI-5 proposal and new routing WG co-chair
by Paolo Moroni 02 Nov '17

02 Nov '17

Dear colleagues, a couple of news from RIPE-75: you might find useful to know about them before the WG minutes are published. 1) Please find enclosed the NWI-5 proposal of the DB working group, which might be of interest for those who use the RIPE DB as input to build BGP filters. The proposal was discussed in the DB working group mailing list and at the RIPE-75 meeting. The DB WG co-chairs have declared it reached consensus and the implementation is progressing. 2) Joao Damas decided to step down as routing WG co-chair; your new co-chair is Ignas Bagdonas. On behalf of the WG, I wish to thank Joao for his many, many years in support of our activities and I welcome Ignas as new co-chair. As always, you can reach us at <routing-wg-chairs(a)ripe.net>. Regards, Paolo Moroni Routing WG co-chair ---------- Forwarded message ---------- From: db-wg [mailto:db-wg-bounces@ripe.net] On Behalf Of William Sylvester via db-wg Sent: Donnerstag, 19. Oktober 2017 17:41 To: William Sylvester via db-wg <db-wg(a)ripe.net> Subject: [db-wg] NWI-5 Out of region ROUTE(6)/AUT-NUM objects implementation request DB-WG Members, Support was shown for the proposal NWI-5 and no objections were raised after this round of discussion. At this time, the chairs request that the RIPE NCC schedule implementation of NWI-5 as described. This request is to remove origin: and flag route objects as specified. The db-wg therefore ask the RIPE NCC to prepare an impact analysis, followed by an implementation plan and timeline for this request and the other issues raised in the problem solution of NWI-5 as follows: 1) Remove the "origin:" authorization requirement. 2) Flag "route:" objects for non-RIPE-managed space with "source: RIPE-NONAUTH" to identify non-authoritative data. Thank you all for your work on this proposal! Kind regards, William & Denis DB-WG co-chairs

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

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? BR, Juan Brenes -- JUAN BRENES BARANZANO Universidad Carlos III de Madrid
