RIPE 79 Routing WG session - important information
by Job Snijders 01 Oct '19

01 Oct '19

Dear Working Group, TL;DR: If you are interested to present on somethign Routing, reach out to us ASAP! In about 16 days we'll have the opportunity to gather in the beatiful city of Rotterdam, Netherlands and teach each other neat things about routing. During the Routing WG slot we can focus on all aspects of IP Routing, routing security, new technologies and new applications of current technologies. This is the stuff Internet is made of! :-) The process to put together this upcoming session's programme is a bit unusual, we've learned that unfortunately some key volunteers are unable to participate this RIPE meeting; as a result Hans Petter Holen asked myself and Rob Evans to help put together a programme. I'm excited to help out, I hope we'll be successful in putting something educational together even though we're operating on fairly short notice. If you have something you’d like to talk about, please send ideas to job(a)ntt.net, rob.evans(a)jisc.ac.uk, along with whether the talk is brief (5-10 minutes) or longer (25-30 minutes including discussion). Rob and I will also go through the archive of presentation proposals submitted to routing-wg-chairs(a)ripe.net, we will analyse the backlog and reach out to the submitters with feedback on their proposal. Kind regards, Job & Rob

BGPplay route collectors in China
by Rafal.Jankowski＠refinitiv.com 19 Aug '19

19 Aug '19

Dear Routing WG, My company has couple of prefixes (listed at the bottom of this e-mail) that are advertised via ASN 1787 to China Telecom (ASN 4809) and China Unicom (ASN 4837). Unfortunately this is not something I could see in BGPlay. I would assume this is because there is no route collector in China. Is there any chance there will be one in the future? 146.242.22.0/24 146.242.24.0/24 146.242.36.0/24 159.104.6.0/24 159.220.16.0/24 159.220.17.0/24 159.220.18.0/24 159.220.20.0/24 159.220.23.0/24 159.220.40.0/24 159.220.68.0/23 159.220.240.0/24 162.8.120.0/24 162.8.125.0/24 192.165.211.0/24 192.165.214.0/24 192.165.215.0/24 PS Apologize for a stupid disclaimer in the e-mail footer and a broken DKIM signature, they are out of my control ________________________________ This e-mail is for the sole use of the intended recipient and contains information that may be privileged and/or confidential.

2018-06 Review Phase (RIPE NCC IRR Database Non-Authoritative Route Object Clean-up)
by Marco Schmidt 16 Aug '19

16 Aug '19

Dear colleagues, Policy proposal 2018-06, "RIPE NCC IRR Database Non-Authoritative Route Object Clean-up", is now in the Review Phase. The goal of the proposal is to delete an non-authoritative object stored in the RIPE IRR, if it conflicts with an RPKI ROA. The proposal has been updated following the last round of discussion and is now at version v3.0. Some of the differences from version v2.0 include: - Provides details about the process how to identify and solve conflicts The RIPE NCC has prepared an impact analysis on this latest proposal version to support the community’s discussion. You can find the full proposal and impact analysis at: https://www.ripe.net/participate/policies/proposals/2018-06 And the draft documents at: https://www.ripe.net/participate/policies/proposals/2018-06/draft As per the RIPE Policy Development Process (PDP), the purpose of this four week Review Phase is to continue discussion of the proposal, taking the impact analysis into consideration, and to review the full draft RIPE Policy Document. At the end of the Review Phase, the Working Group (WG) Chairs will determine whether the WG has reached rough consensus. It is therefore important to provide your opinion, even if it is simply a restatement of your input from the previous phase. We encourage you to read the proposal, impact analysis and draft document and send any comments to <routing-wg(a)ripe.net> before 12 September 2019. Kind regards, Marco Schmidt Policy Officer RIPE NCC

Note on ripe-580: BGP flap damping
by Sebastian Wiesinger 15 Aug '19

15 Aug '19

Hi, just a heads up in regard to ripe-580. It states that "The default values used in current implementations of RFD apply a penalty of 1000 each time a route flaps". At least for Juniper that is not the case. Or to quote them directly: A figure-of-merit value of zero is assigned to each new route. The value is increased each time the route is withdrawn or readvertised, or when one of its path attributes changes. With each incident of instability, the value increases as follows: Route is withdrawn: 1000 Route is readvertised: 1000 Route's path attributes change: 500 Note: Other vendors' implementations for figure-of-merit increase the value only when a route is withdrawn. The Junos OS implementation for figure-of-merit increases the value for both route withdrawal and route readvertisement. To accommodate other implementations for figure-of-merit, multiply the reuse and suppress threshold values by 2. So yeah, if you want to use ripe-580 on Junos gear you should probably multiply the suppress/cutoff value by 2. Regards Sebastian -- GPG Key: 0x58A2D94A93A0B9CE (F4F6 B1A3 866B 26E9 450A 9D82 58A2 D94A 93A0 B9CE) 'Are you Death?' ... IT'S THE SCYTHE, ISN'T IT?

New BGP hijack & visibility tool “BGPalerter”
by Job Snijders 14 Aug '19

14 Aug '19

Dear Routing WG, Recently NTT investigated how to best monitor the visibility of our own and our subsidiaries’ IP resources in the BGP Default-Free Zone. We were specifically looking how to get near real-time alerts funneled into an actionable pipeline for our NOC & Operations department when BGP hijacks happen. Previously we relied on a commercial “BGP Monitoring as a Service” offering, but with the advent of RIPE NCC’s “RIS Live” streaming API [1] we saw greater potential for a self-hosted approach designed specifically for custom integrations with various business processes. We decided to write our own tool “BGPalerter” and share the source code with the Internet community. BGPalerter allows operators to specify in great detail how to distribute meaningful information from the firehose from various BGP data sources (we call them “connectors”), through data processors (called “monitors”), finally outputted through “reports” into whatever mechanism is appropriate (Slack, IRC, email, or a call to your ticketing system’s API). The source code is available on Github, under a liberal open source license to foster community collaboration: https://github.com/nttgin/BGPalerter If you wish to contribute to the project, please use Github’s “issues” or “pull request” features. Any help is welcome! We’d love suggestions for new features, updates to the documentation, help with setting up a CI regression testing pipeline, or packaging for common platforms. Kind regards, Job & Massimo NTT Ltd [1]: https://ris-live.ripe.net/

Extending RPKI-Router protocol to do more
by Iljitsch van Beijnum 11 Jul '19

11 Jul '19

[Posted to sidrops, grow and RIPE routing-wg] Hi all, A few weeks ago I wrote a draft on extending RPKI to make it possible to validate the full AS path rather than just the origin AS. Rather than ignore other work in this area such as ASPA and AS Cones, I've decided to focus on the thing that all these efforts will benefit from: extensions to the RPKI-Router protocol so that more types of filtering become possible under the RPKI model than just origin validation as per RFC 6811. I think the RPKI model is a powerful one: you run the software that uses complex algorithms on a small set of central boxes. This is very flexible software that can be changed quickly (often open source). Then you send filters over to the routers using very well-defined semantics, so you know exactly what the routers are going to do and the risks are minimal, with no need to keep changing the router implementations when there are new validation mechanisms. My additions are: - a way to filter entire AS paths (such as created by ASPA or my PathRPKI draft) - a way to allow prefixes from a given set of ASes, which could be used to implement a system like AS Cones - a way to deny prefixes from a given set of ASes, which could be used to react to route leaks etc on the fly These are just examples, I'm sure there are many different things that could be done with these filter extensions. I wrote a draft about the whole thing, but draft submissions are currently closed so read it here for now: http://www.muada.com/drafts/draft-van-beijnum-sidrops-rpki-rtr-ext-00.txt <http://www.muada.com/drafts/draft-van-beijnum-sidrops-rpki-rtr-ext-00.txt> I'm very interested to hear what you think.

Path validation with RPKI
by Iljitsch van Beijnum 20 Jun '19

20 Jun '19

Dear secure interdomain routing operators, I've been away from the IETF for a while, and I'm new to this mailing list, so I'm not up to date with what's been happening here. I'm not going to let that stop me :-) but apologies if I retread worn out paths. Also, I'm not sure if this work ultimately fits this wg, but I think this is the right place for an initial discussion. I'm also starting this discussion on the RIPE routing-wg list. A few weeks ago there was a significant route leak through Safe Host and China Telecom. This keeps happening. I think we can stop these route leaks with a relatively modest change to RPKI: by combining the ASes the origin trusts and the ASes the operator of an RPKI relying party server trusts, we have a list of all the ASes that may legitimately appear in the AS path as seen from this particular vantage point. I believe deployment will be relatively easy, as it works for the two ASes at both ends even if ASes in the middle don't participate. So this means a change to the ROA format, a change to the RPKI-router protocol, and of course changes to the software involved. Here is the draft: https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/ <https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/> There is path filter example code in the appendix to show that this part is easy. :-) In case you want to try this out but don't want to compile it yourself, (mostly) the same code is also running here: http://bgpexpert.com/pathrpki/ <http://bgpexpert.com/pathrpki/> Probably not too much new information for this group, but some background: http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html <http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html> Note that this is significantly different from the AS-Cones proposal. AS-Cones is a way for transit ASes to filter their peers (and maybe their customers). RPKI path validation is everyone filtering all prefixes they see, regardless of whether these prefixes come in through peering or transit. However, there is no reason the two can't be deployed side by side. I've also read the ASPA draft, and although there are some overlap between ASPA and RPKI path validation, I'm not entirely clear on the details but they seem to be very different. Iljitsch

Dear routing-wg'ers, A few weeks ago there was a significant route leak through Safe Host and China Telecom. This keeps happening. I think we can stop these route leaks with a relatively modest change to RPKI: by combining the ASes the origin trusts and the ASes the operator of an RPKI relying party server trusts, we have a list of all the ASes that may legitimately appear in the AS path as seen from this particular vantage point. I believe deployment will be relatively easy, as it works for the two ASes at both ends even if ASes in the middle don't participate. So this means a change to the ROA format, a change to the RPKI-router protocol, and of course changes to the software involved. I'm interested to hear what everyone thinks of this, and especially what the developers of implementations think. Here is the draft with the protocol modifications: https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/ <https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/> There is path filter example code in the appendix to show that this part is easy. :-) In case you want to try this out but don't want to compile it yourself, (mostly) the same code is also running here: http://bgpexpert.com/pathrpki/ <http://bgpexpert.com/pathrpki/> And if you need more background: http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html <http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html> Note that this is significantly different from the AS-Cones proposal.
