looking for online RPKI dashboard / looking glass?
by Gert Doering 30 May '18

30 May '18

Hi, is there an online looking glass to see RPKI status for ``everything a given AS announces / transits''? Say, I want to check my AS (AS5539) plus all downstream customers (... visible at the vantage point of said tool, of course). I have found whois.bgpmon.net, which I can use by feeding prefix after prefix into whois and then parsing the reply, but that's a bit cumbersome for "give me all there is to know". Basically show ip bgp reg _5539_ and then for each prefix returned, check RPKI status, flag green/red/yellow. The RIPE LIRportal RPKI dashboard sort of does the job for all ASes that I have created ROAs for (so, if I maintain my customer ROAs, I would see them) but I cannot query an arbitrary AS, or "the whole customer cone". (I expected RIPE Stats to have something like this in the BGP widget, but to my surprise, no...) Gert Doering -- NetMaster -- have you enabled IPv6 on something today...?

ROAs and route objects and filters
by Sandra Murphy 17 May '18

17 May '18

There was a discussion in the routing wg on Monday of converting ROAs into IRR route objects for easy incorporation into the scripts many ISPs have for building filters from IRR data. (I wanted to share this in time for the routing wg meeting Thursday morning, but woke in the teeny hours of Thu night/morning to find that the household Internet connection was down. Diagnosis and switch to backup plan did not get me connected until the opportunity was lost.) The ability to translate ROAs into route objects was recognized early on and is/was incorporated into at least three RPKI implementations that I know of. If I recall correctly, Ruediger Volk was the first to suggest that strategy. Geoff Huston made an interesting observation when this was mentioned in a SIDR working group meeting. There might be an unintended consequence when adding ROA-based-route objects into the filter generation mix, depending on the ISP's filter generation rules. Suppose you had an AS XYZ that created no route objects. Suppose you had an ISP that generated filters from IRR data. When the list of route objects is null, the ISP might generate a deny all filter and it might generate a permit all filter. Suppose then that a prefix holder mistakenly generated a ROA for one of its prefixes for AS XYZ. The list of route objects for AS XYZ is now not null. If the ISP had previously generated a deny all filter, the filter now permits one prefix. Not much damage there. If the ISP had previously generated a permit all filter, the filter now permits just one prefix. That’s a big change. This presently doesn’t happen with RIPE route objects, because the RIPE model is that route objects have to have the permission of both prefix holder and ASN holder. So the mistake would not get registered. [I believe this scenario also works if the IRR rule for route object registration is only that it has the permission of the prefix holder. According to the presentation Monday, that is the case today in some IRRs. A prefix holder might mistakenly register a route object for AS XYZ.] Any ISP that generates a permit all filter when the route object list is null should be aware of this corner case and take appropriate care in their filter generation. I suspect that generating a deny all filter is much more common. —Sandy

Questionnaire/survey on the ARTEMIS BGP Prefix Hijacking Defense System
by Vasileios Kotronis 15 May '18

15 May '18

Dear Routing WG members/operators, we are researchers from FORTH, Greece. In collaboration with CAIDA, we are working on a BGP hijacking defense system called ARTEMIS ( www.inspire.edu.gr/artemis ). ARTEMIS is funded by RIPE NCC Community Projects 2017 and will be presented during the RIPE76 Routing WG session (Thursday 17 May, 9.00 am). We would really appreciate your feedback on the following related questionnaire/survey about ARTEMIS. Survey URL: https://goo.gl/forms/PETugofb2wspSPez2 We would be happy to answer related questions you might have. Best regards, Vasileios -- ======================================= Vasileios Kotronis Postdoctoral Researcher, member of the INSPIRE Group INSPIRE = INternet Security, Privacy, and Intelligence REsearch Telecommunications and Networks Lab (TNL) Foundation for Research and Technology - Hellas (FORTH) Leoforos Plastira 100, Heraklion 70013, Greece Tel: +302810391241 Office: G-060 e-mail : vkotronis(a)ics.forth.gr url: http://inspire.edu.gr =======================================
