A study on community-triggered updates in BGP
by Thomas Krenc 16 Oct '20

16 Oct '20

Dear NANOG, As a team of researchers from NPS and TU Berlin, we are investigating the impact of BGP community attributes on the update behavior between ASes. We find that when a route is associated with multiple distinct community attributes it does not only lead to multiple announcement at the tagging AS, but also at neighboring ASes, if communities are not filtered properly. This behavior is wide-spread. In order to better understand our observations, we have performed a series of laboratory experiments using Cisco IOS, Junos OS, as well as the BIRD daemon. We find that - by default - all tested routers generate announcements with changing community attributes, even when other attributes do not change. In addition, when communities are filtered at egress, Cisco und BIRD send duplicate announcements (Juniper does not). Since our findings are limited to observations in public data as well as few router implementations, we would like to share our research and kindly ask you to have a look at: https://www.cmand.org/communityexploration/ There, we provide some resources documenting our research, as well as open questions. We greatly appreciate any feedback and insights you can offer. Also, please don't hesitate to contact us directly: communityexploration AT cmand DOT org best regards Thomas Krenc Postdoctoral Researcher Naval Postgraduate School

Residential GPON last mile for network engineers (Telus AS852 and others)
by Eric Kuhnke 15 Oct '20

15 Oct '20

With the growth of gigabit class single fiber GPON last mile services, I imagine a number of people reading the list must have subscribed to such by now. Something that I have observed, and shared observations with a number of colleagues, is that very often a person who works for ($someAS) lives in a location where you are effectively singlehomed to ($someotherAS). Maybe you bought your house before you got a job with your current employer, or maybe the network you work for doesn't do residential last mile service at all. Perhaps you work remotely for a regional sized entity that's a long distance away from where you live. Therefore necessitating a choice of service from whatever facilities based consumer-facing ISP happens to service your home. For example, in Seattle, a number of people discovered that they could keep the Centurylink GPON ONT, and remove the centurylink-provided router/modem combo device. Provided that they were able to configure their own router (small vyatta, pfsense box, mikrotik, whatever) to speak a certain VLAN tag on its WAN interface and be a normal PPPoE / DHCP client. I'm sure there are a lot of people who prefer to run their own home router and wifi devices, and not rely upon a ($big_residential_isp) provided all-in-one router/nat/wifi box with opaque configuration parameters, or no ability to change configuration at all. Any insights as to what the configuration of the Telus AS852 GPON network looks would be helpful. Or other observations in general on technically-oriented persons who are doing similar with other ILECs.

FCC FUSF charges clarification
by Nuno Vieira 15 Oct '20

15 Oct '20

Hello All, Need some help/insight from you guys on this: Company A is an incorporated in Europe, where it main business is, however it has some pops within USA. Company A uses services from several companies within USA. (carrier H, C, Z, G, L, etc..) all in the United States to remotelly connect his stuff. All companies charge company A the agreed fees, except company Z. Company A has two services with company Z. One is IP Transit (in SFO, CA) Other is a Metro Wavelenght (also in SFO, CA) Company Z charges company A on top of agreed services: for IP Transit (other charges representing roughly 6%) for the wavelenght (a lot of charges, such as the ones described below) - FCC Regulatory Fee (wireline) - Fed Universal Service Fund - CA High Cost Fund A - CA Teleconnect Fund - CA TRS - CASF - Universal Lifeline Telephone Service Charge - Utility Users Tax nevertheless company A DOES NOT have any "Telephone" services or whatsoever in the USA. At the end of the day what was meant to be a fixed bill is in fact a 20% higher one... So... my question IS: Is an European company (or whatsoever foreign wholesale company) WITHOUT ANY customers in USA liable to pay those taxes to the carrier ? Thanks for all you help. /Nuno

We had horrible experiences with them a long time ago. Inexplicable packet loss problems, route weirdness, so we dumped them. A couple of years ago we decided to give them another try (I was skeptical), but so far it has been just fine. At 07:29 PM 13/10/2020, Aaron Gould wrote: >Do yâall like HE for Internet uplink?

by John Curran 14 Oct '20

14 Oct '20

NANOGers - FYI - ARIN 46 Virtual Meeting will start at today at noon ET. The meeting will be held via Zoom, and details on the schedule policy discussions, presentations, meeting materials and registration are attached. Best wishes! /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Subject: [arin-announce] ARIN 46 Will Be Here Soon – Get Ready! Date: 13 October 2020 at 3:33:11 PM EDT To: "arin-announce(a)arin.net<mailto:arin-announce@arin.net>" <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> This week kicks off the ARIN 46 Virtual Public Policy and Members Meeting, where we will be in the thick of important community discussions on the following policies: - Recommended Draft Policy ARIN-2020-1: Clarify Holding Period for Resources Received via 4.1.8 Waitlist - Recommended Draft Policy ARIN-2020-2: Reinstatement of Organizations Removed from Waitlist by Implementation of 2019-16 - Recommended Draft Policy ARIN-2020-3: IPv6 Nano-Allocations - Recommended Draft Policy ARIN-2020-5: Clarify and Update Requirements for Allocations to Downstream Customers - Draft Policy ARIN-2020-6: Allowance for IPv4 Allocation “Swap” Transactions via 8.3 Specified Transfers and 8.4 Inter-RIR Transfers - Draft Policy ARIN-2020-7: 4.4 gTLD micro-allocation clarification - Draft Policy ARIN-2020-8: Clarify and Update 4.2.1.2 Annual Renewal Fee All draft policy text is available at: https://www.arin.net/participate/policy/drafts/ The ARIN 46 agenda will also feature several other informative sessions, including updates on routing security, services, our customer satisfaction survey, and much more. If you attended ARIN 45 in June, you were one of the lucky ones to experience our first completely virtual meeting. While we received great feedback on how that meeting went, we’re excited to introduce a few enhancements we’ll be making to ARIN 46 now that we have more planning time and experience. - We plan to allow attendees into Zoom 15 minutes before the meeting starts each day so folks can say hello to one another. We will be providing some music and fun slides during this time for you to enjoy as well! - During the 30-minute breaks on 14 and 15 October, you can stick around for a short, 10-minute seated stretching session at the beginning of each break. - On 14 October, we’ll be playing “Buzzword Bingo.” Whether you are a rookie or a seasoned pro, this is your chance to shine and get comfortable with the terminology used in our community. We’ll be sending out bingo boards in advance, which you will fill in with a word bank of buzz words you typically hear at ARIN meetings. - On 15 October we’ll be hosting an ARIN Trivia game. Newcomers are welcome to join in! It’s a great way to learn more about ARIN. We will also be hosting six breakout sessions at the end of the day on 14 October. Participants will be able to visit as many rooms as they want during the session and can move around or leave at any point. These will act just like the table topics we normally have during lunch. Folks can access all breakout rooms by visiting the following URL at the close of the meeting on 14 October: https://arin.zoom.us/j/92748378149?pwd=UENsQzVqYTgzd0FsVlUvQ1BuOU4rUT09 We want to make sure you can participate in the meeting using all the functionality the latest version of Zoom has to offer. For an optimal experience, we recommend that you run Zoom Version 5.3.0 or higher. One hour before the meeting starts each day, registered attendees will receive an email from “ARIN no-reply(a)zoom.xn--us-x2t with the URL for that day’s session. These links are not identical, so be sure you use the correct one for each day. Leading up to the meeting, we want to make sure you are ready to participate. To help you prepare, ARIN has published all of the meeting materials online for you to review or download beforehand. Just visit: https://www.arin.net/ARIN46_materials Need a refresher on ARIN’s Policy Development Process (PDP) before joining us to talk policy? You may want to check out the on-demand version of our PDP webinar, which covers the entire process, start to finish: https://www.arin.net/reference/training/webinars/#the-policy-development-pr… View the full agenda and register today for this meeting while there’s still time: https://www.arin.net/ARIN46 Please contact us at meetings(a)arin.net if you have any questions.

They have a pretty capable tools development team in house. They don't do communities other than RTBH. They are doing ROV, which I think helped clean up some BGP noise I used to see, but I've not checked lately. They also know a thing or two about IPv6, plus carry traffic for all those IPv6 tunnel broker setups and probably at least if not more of the 6to4 traffic for whatever is left of that if it matters to you (and I might argue you might want to consider not accepting the 6to4 associated prefixes nor carry that traffic). Make sure you maintain another way to get to Cogent-only prefixes. John
