I can't comment on the direct comparison of the SLX9540, but we have 8x 7280SR deployed across our network (just migrated off all the Brocades we had) and have had amazing success with them. The number of informational or "show" commands isn't as extensive as some of the others that have been around for a while and the output of some of them is a little jarring, but otherwise I have no complaints. All of my BGP sessions (200-300 IX sessions, 2 transit providers, 28 iBGP) are fully populated in <10 seconds (i know many of your networks are much larger than ours). As for pricing, I don't have list, but for the box, memory upgrade, and routing license we paid much less than 100k -- Of course the port density Feel free to reach out directly for more specific information :) Mike On Fri, Mar 8, 2019 at 7:00 AM <nanog-request(a)nanog.org> wrote: Message: 8 Date: Thu, 7 Mar 2019 21:44:34 -0600 From: Colton Conor <colton.conor(a)gmail.com> To: "Kaiser, Erich" <erich(a)gotfusion.net> Cc: NANOG list <nanog(a)nanog.org> Subject: Re: Arista Layer3 Message-ID: <CAMDdSzOpE6Cnz+JUH=+31a2VGDcqQ5qi2nA16h8ethce1RxfvQ(a)mail.gmail.com> Content-Type: text/plain; charset="utf-8" So how does the 7280SR-48C6 compare to the SLX9540? They are the same Broadcom chipset right? So the real question, is how does the product differ in software?

Folks, The Internet Society has posted the "IPv6 Security Frequently Asked Questions (FAQ)" I authored. The document is available (in HTML, and also easy-to-print PDF) at: https://www.internetsociety.org/deploy360/ipv6/security/faq/ If you think there are other questions that should be added, or have comments on the answers, please do let me know -- the document can eventually be revised. Thanks! Cheers, -- -- Fernando Gont SI6 Networks e-mail: fgont(a)si6networks.com PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492

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.

Best practices for BGP Communities
by Joshua Miller 07 Mar '19

07 Mar '19

Hello everybody, A while back I read somewhere that transit providers shouldn't delete communities unless the communities have a specific impact to their network, but my google-fu is failing me and I can't find any sources. Is this still the case? Does anyone have a source for the practice of leaving unknown communities alone or deleting them? Best, Josh

March is Severe Weather Month - Plan Ahead for Disasters
by Sean Donelan 06 Mar '19

06 Mar '19

Network operators are involved in most weather disasters. March is Severe Weather Month in the U.S. The National Weather Service and many states use severe weather month to encourage public planning and preparedness. https://www.ready.gov/ https://www.weather.gov/wrn/ Remember, your Amazon Alexa, Google Assistant, Applie Siri smart speakers, smart TVs, and smart assistants won't practively warn you about emergency alerts or weather warnings. Amazon Alexa will tell you about weather warnings, but only when you ask about the weather. The FEMA National Advisory Council published its recommendations for Modernizing the Nation's Public Alert and Warning System, which included adding alerts to new technologies. https://www.fema.gov/media-library/assets/documents/177192 "Ensure people can receive and understand geo-targeted IPAWS messages in numerous ways, including social media, mobile aps, automotive GPS units, driverless cars and intelligent in-home automated systems (e.g., Smart Speakers)." I also have some suggestions for Wireless Emergency Alerts, in case any Apple iOS or Google Android developers are reading. 1. Improving the WEA Imminent Threat Class and Categories 2. Redefining the Child Abduction Emergency/AMBER class 3. Do Not Disturb WEA Behavior for Less Severe Alerts 4. Revising Sample WEA Options Menu 5. Default WEA class names for mobile device user interfaces https://www.donelan.com/WEA-Improvements.pdf https://www.donelan.com/eas.html
