RIS anchor/beacon changes
by Martin Pels (RIPE NCC) 02 Feb '24

02 Feb '24

Dear all, In the coming months we will be making several changes in the prefix advertisements by RIS Route Collectors. These changes were discussed previously on RIPE Labs[0]. January 2nd 2024 ---------------- The following BGP announcements will be disabled: * IPv4 anchor+beacon announcements on RRC04, RRC07, RRC10, RRC13, RRC14, RRC15, RRC16, RRC21 and RRC22 * IPv4 anycast failover simulation beacon (84.205.72.0/24) on RRC03 and RRC14 All IPv6 anchor+beacon announcements will remain. February 1st 2024 ----------------- We will be enabling the following new prefix advertisements: * A single anycast IPv4 and IPv6 anchor+beacon pair per RIR region, advertised from each RRC in this region. * An anycast IPv4 /25 and /28 anchor, advertised from one RRC per RIR region * An anycast IPv6 /56 and /64 anchor, advertised from one RRC per RIR region To accommodate these changes we will also modify the encoding used in the BGP AGGREGATOR attribute. For full details and an overview of all anchor and beacon prefixes, please refer to our updated documentation[1]. Kind regards, Martin Pels RIPE NCC [0] https://labs.ripe.net/author/emileaben/ris-beaconing-shining-a-light-on-bgp… [1] https://ris.ripe.net/docs/routing-beacons

Changes to the rpki archives on ftp.ripe.net
by Ties de Kock 26 Jan '24

26 Jan '24

Dear colleagues, As you may know, the RIPE NCC publishes daily RPKI dumps for all trust anchors on ftp.ripe.net/rpki. Today, we have made some changes to this longitudinal dataset. We have added: * The compressed JSON output of a validator (output.json.xz). We added this because it contains validated ASPA and BGPsec payloads. * A compressed version of the CSV file of ROAs (roas.csv.xz) * A xz compressed archive of the validated and unvalidated objects (repo.tar.xz) We made this change because it significantly reduces the size of the files. At this point, we do not plan to re-compress historic files. However, to realise the savings, we must stop producing the larger version at some point and clean up the "duplicate" files from the transition period. For now, we will create the old (roas.csv, repo.tar.gz) and new (roas.csv.xz, repo.tar.xz) side by side during a transition period. We plan to stop creating the old format after a transition period of at least a month, taking into account the feedback we receive. We will inform you when this happens. Ties de Kock Specialist Software Engineer RIPE NCC

Possible new RIS Beacon? (Alternating visible pair)
by Ben Cartwright-Cox 22 Jan '24

22 Jan '24

Hey everybody, On my seemingly never ending task to find all "stuck" BGP sessions, I feel like there is an interesting thing that could be done for the RIPE RIS Beacons, and that is a pair of prefixes that alternate between being visible and invisible (IE: unannounced). I looked at the current estate of beacon prefixes and couldn't find anything that would fit this use case already. This would be useful to be able to tell if a prefix or session has got a stuck prefix at that current moment in time, by being able to check the time and see if the presence of a prefix shouldn't be visible. In the interests of full disclosure this would be very useful for bgp.tools to instantly “spot check” BGP feeds to see if they have stuck prefixes or not. What does everybody think? This should "only" require two /24s and two /48s, and I think this would also help researchers see the severity of stuck sessions in a much more measurable way than having to wait for hours for the beacons to go on or off! (Apologies if this is not the right place for this kind of discussion, but there were previous mails about the beacons here, so I figured here was a good place) Cheers Ben
