New RIS Remote Route Collectors at InterLAN Bucharest, Equinix Singapore
by Colin Petrie 04 Jul '18

04 Jul '18

Dear colleagues, The RIPE NCC is pleased to announce two new Remote Route Collectors (RRCs) for the Routing Information Service (RIS). RRC22 is now online at InterLAN in Bucharest. We would like to thank InterLAN for their help and support. RRC23 is now online at Equinix Singapore in Singapore. We would like to thank Equinix for their help and support. The data from these new collectors is already available via RIPEstat, and the raw data is available in the archives. Peering with RIS ---------------- If you would like to peer with us, please fill in the form at: http://www.ris.ripe.net/cgi-bin/peerreg.cgi For more information about peering with RIS, please see: https://www.ripe.net/analyse/internet-measurements/routing-information-serv… About RIS ------------- RIS aims to collect and store Border Gateway Protocol (BGP) routing information and make it publicly available for the Internet community. The RIPEstat tools that provide access to this data can help network operators troubleshoot routing problems by providing eBGP data collected over time without being limited to a single BGP view. RIS deploys RRCs at major Internet exchanges, where they peer with other networks. At this time, RIS has more than 750 peers at 22 different Internet exchanges. For more information, please see: https://ripe.net/ris/ If you have any further questions, please contact <ris at ripe.net> Kind Regards, Colin Petrie RIPE NCC

Fwd: Time to add 2002::/16 to bogon filters?
by Job Snijders 28 Jun '18

28 Jun '18

Dear working group, Feedback welcome - should 2002::/16 still be accepted in the DFZ? Kind regards. Job ---------- Forwarded message --------- From: Job Snijders <job(a)ntt.net> Date: Mon, 18 Jun 2018 at 23:08 Subject: Time to add 2002::/16 to bogon filters? To: NANOG [nanog(a)nanog.org] <nanog(a)nanog.org> Dear all, TL;DR: Perhaps it is time to add 2002::/16 to our EBGP bogon filters? It is kind of strange that in the default-free zone (where we don’t announce defaults to each other) - we will propagate what is effectively an IPv4 default-route, in the IPv6 DFZ. IETF has politely abandoned the prefix: https://tools.ietf.org/html/rfc7526 Wes George highlighted operational problems from accepting 2002::/16 on the data-plane slide 6: http://iepg.org/2018-03-18-ietf101/wes.pdf Is there still really any legit reason left to accept, or propagate, 2002::/16 on EBGP sessions in the DFZ? Kind regards, Job

New on RIPE Labs: Measuring the Adoption of RPKI Route Origin Validation
by Mirjam Kuehne 19 Jun '18

19 Jun '18

Dear colleagues, The number of Resource Certificates and ROAs is steadily growing, especially in the RIPE NCC service region. However, it remains unclear how widely BGP speakers on the Internet are actually using route origin validation (ROV) to drop or de-preference invalid announcements. In this new article on RIPE Labs, Andreas Reuter and his colleagues present their public monitoring platform - the ROV Deployment Monitor - and the methodology behind it. https://labs.ripe.net/Members/andreas_reuter/measuring-the-adoption-of-rpki… Kind regards, Mirjam Kühne RIPE NCC
