Equinix SV8 Facebook IPv6 router 2001:504:D::47/64 constantly bouncing sessions
by Peter Kranz 05 Dec '17

Are other SV8 peering exchange participants seeing problems with Facebooks 2001:504:D::47/64 router in the SV8? Been seeing this for over 48 hours now. No issues with other SV8 peers, or Facebooks other IPv6 router in the facility.

Lanner Devices - NCA-5510
by Raymond Burkholder 05 Dec '17

05 Dec '17

Hello, A number of people have been suggesting Lanner boxes for routing. I have used FW-7543A and FW-7573A boxes with Debian with no issues. I am currently trying the NCA-5510 model with NCS2-IGM806B (XL710) and NCS2-IXM407A (I350) cards with a standard Debian Stretch installation. I was hoping that it would be as easy as installing the operating system, turning ports up, and getting a working network. It was like that with the other models. Not with this model. There seems to be a bunch of different BIOS combinations which give different (bad) results. And for the combinations I've tried, I can't seem to get the XL710 card to work properly. Maybe I should have gone with the 82599 card instead. In addition, the I210 based management port also isn't coming up properly, always some sort 'interface reset' error. Which, with some bios settings, I get on the I350 cards as well. If someone has a similar model and/or configuration, what sort of BIOS/Kernel settings have you used to get something operationally stable? Any particular Kernel versions work best? I tried 4.9.51, and 4.14.3. It seems to take about 48 hours to get turn arounds from Taiwan engineering, which I am currently trying to escalate from a sales office, but was hoping, in the meantime, someone else might have some experiences to share? I can provide console / kernel messages to show what I am encountering for those interested. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

100G - Whitebox
by Mike Hammett 04 Dec '17

04 Dec '17

I first sent to an IX-specific mailing list, but as I have yet to see the message hit the list, I figured I would post it here as well. We've had multiple requests for 100G interfaces (instead of Nx10G) and no one seems to care about the 40G interfaces we have available. Looking at cost effective options brings us to whitebox switches. Obviously there's a wide range of hardware vendors and there are a few OSes available as well. Cumulus seems to be the market leader, while IPinFusion seems to be the most feature-rich. We're not doing any automation on the switches at this time, so it would still need decent manual configuration. It wouldn't need a Cisco-centric CLI as we're quite comfortable managing standard Linux-type config files. We're not going all-in on some overlay either given that we wouldn't be replacing our entire infrastructure, only supplementing it where we need 100G. I know that LINX has gone IPinfusion. What OS would be appropriate for our usage? I'm not finding many good comparisons of the OSes out there. I'm assuming any of them would work, but there may be gotchas that a "cheapest that meets requirements" doesn't quite unveil. Any particular hardware platforms to go towards or avoid? Broadcom Tomahawk seems to be quite popular with varying control planes. LINX went Edgecore, which was on my list given my experience with other Accton brands. Fiberstore has a switch where they actually publish the pricing vs. a bunch of mystery. Thoughts? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

BGP next-hop self benefits
by craig washington 04 Dec '17

04 Dec '17

Hello everyone, Question, what are the true benefits to using the next-hop self feature, doesn't matter what vendor. Most information I see is just to make sure you have reach-ability for external routes via IBGP, but what if all your IBGP knows the eBGP links? Is there a added benefit to using next hop self in this situation? Any feedback is much appreciated, either for the question specifically or whatever else you got 😊, L3VPN's or underlying technology that has to have that. Thanks
