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/
