Arista Layer3
by Romeo Czumbil 09 Mar '19

09 Mar '19

So I've been using Arista as layer2 for quite some time, and I'm pretty happy with them. Kicking the idea around to turn on some Layer3 features but I've been hearing some negative feedback. The people that I did hear negative feedback don't use Arista themselves. (they just heard....) So do we have any Arista L3 people out here that can share some negatives or positives? Use case: Just some MPLS IPv4/IPv6 routing, l2vpn OSPF/BGP Maybe 20k routes (no full internet routes) 7050 Series 7280 Series -Romeo

WIndows Updates Fail Via IPv6
by Mark Tinka 07 Mar '19

07 Mar '19

Hi all. Anyone ever figured out why Windows updates fail when the computer has an IPv6 connection? Google has tickets and tickets of this to and outside of Microsoft since 2013, with no real solution or answer as to what the problem actually is. In essence, many of the solutions out there point toward making sure the updates do not occur over IPv6, which, in effect, is the same as disabling it. I have a family PC at home running Windows 10 Pro, and noticed updates would fail in recent months. It took me a moment to realize that this started happening only after I enabled IPv6 in the TCP/IP stack. Disabling it immediately solves the issue. Quite odd that this is happening in 2018... Mark.

adding graphs for actually unreachable RPKI INVALID prefixes to RPKI Monitor?
by nusenu 14 Feb '19

14 Feb '19

Dear NIST RPKI Monitor Team, thanks for creating and maintaining the RPKI Monitor https://rpki-monitor.antd.nist.gov/#rpki_adopters I've seen your graphs in multiple routing security presentations :) What do you think about adding graphs that show the amount of actually unreachable prefixes and IP space? (prefix where no alternative valid/unknown announcement exists) I think such graphs would help us focus on those prefixes that we should have to tackle first. This page contains examples of INVALID prefixes that would still be reachable in a route origin validating environment (see the RPKI validator screenshots): https://medium.com/@nusenu/towards-cleaning-up-rpki-invalids-d69b03ab8a8c kind regards, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

Amazon Peering
by Darin Steffl 30 Jan '19

30 Jan '19

Hey all, Does anyone have a direct contact to get a peering session established with Amazon at an IX? I sent a peering request Dec 2017 and two more times this Sept and Nov with no response. I sent to peering(a)amazon.com and received one automated response back so I know they received my email but nothing since. -- Darin Steffl Minnesota WiFi www.mnwifi.com 507-634-WiFi <http://www.facebook.com/minnesotawifi> Like us on Facebook <http://www.facebook.com/minnesotawifi>

IPv6 Residential Deployment Survey
by John Curran 24 Jan '19

24 Jan '19

NANOGers - If you are providing residential Internet service with IPv6 (or are a customer of same), please take a moment to complete Jordi’s survey - this will help provide insight into the actual technical practices being used in residential IPv6 deployment. More details in attached email - Thanks! /John Begin forwarded message: From: John Curran <jcurran(a)arin.net<mailto:jcurran@arin.net>> Subject: [arin-ppml] IPv6 Residential Deployment Survey Date: May 22, 2016 at 6:24:17 AM GMT+2 To: ARIN PPML <ppml(a)arin.net<mailto:ppml@arin.net>> Folks - Jordi Palet Martínez is conducting a brief survey regarding IPv6 deployment in residential Internet service. Having insight into the various practices that are in use may help to inform IPv6 number resource policy development, and thus I ask that you take a moment to complete the survey if you are providing such services (whether production or trial basis.) Jordi notes - "The results will be published and updated every month or so - No personal data will be published. (If you know your network, it takes less than 2 minutes to complete it) The survey can be responded even if is not yet a commercial service, and customers can also respond, not just the ISP. However, to avoid duplicate data, make sure to include the country and ISP name.” The IPv6 Residential Deployment Survey may be found here - <http://survey.consulintel.es/index.php/175122> Thanks! /John John Curran President and CEO ARIN

Anyone using AT&T's ECOMP/ONAP?
by adamv0025＠netconsultings.com 18 Jan '19

18 Jan '19

Hi gents, I'm looking for physical network services orchestration framework for network service providers that could later be used/extended to orchestrate other areas of the business (virtualized services in DC, etc..). So far it appears to me that there's no such ready-made commercial product on the market that would contain all the building blocks I'd be interested in (well especially the easy to use service designer tool). ECOMP and now OANP seem to have it all and much more I'm just curious if anyone is using it in anger (or parts of it for that matter) for orchestration/design/automation of services on physical network. I'd like to hear some stories from trenches with regards to the implementation, but I'd be also interested in your thoughts in case you just assessed the tool for implementation (why did liked not liked about it). Thank you adam netconsultings.com ::carrier-class solutions for the telecommunications industry::

L3 Network topology in YANG
by Yannis Mitsos 07 Dec '18

07 Dec '18

All, I was wondering if there is any network operator who exposes (dynamically?) its topology in YANG based on RFC8346 [1]. I understand that for commercial operators and purposes, may not be of any substantial value. We are assessing some available tools[2],[3],[4] on how to achieve this but we would like to know if there is any success story out there. Regards, Yannis [1] https://tools.ietf.org/html/rfc8346 [2] https://github.com/robshakir/pyangbind [3] https://github.com/YangModels/yang.git [4] https://developer.cisco.com/site/ydk

Security Track @ NANOG 75 Call for Participation
by John Kristoff 06 Dec '18

06 Dec '18

[ Apologies if you saw this elsewhere already - jtk ] Friends, colleagues, fellow operators, The network security track, formerly known as the ISP security BoF, has plans to return at NANOG 75 in San Francisco February 18-20. I will be your track facilitator. I have a small handful of topics I'm soliciting from some folks directly, but options are good, and I may be missing something important. If you haven't heard from me already, then I want to hear your ideas or proposals. This is a good, casual place to go with netsec related ideas, tools, or case studies. Here is an incomplete list of relevant topics to stir your thoughts: * IRRs, BGPSEC, and RPKI * DDoS attacks and mitigation * Botnet case studies * ISP incident response tools * Network censorship and privacy * Threat sharing frameworks * Network equipment configuration/default BCPs * Spoofing, amplification, reflection threats * ...insert your idea here John
