Hi all! Can anybody recommend any good resources on TRILL? Particularly anything that addresses do's and don'ts or any problems and pitfalls. Also any experiences deploying and using TRILL in networks that anybody would like to share would be welcome. For clarity, this is the TRILL I'm referring to: https://en.m.wikipedia.org/wiki/TRILL_(computing) Jared

nanog: SixXS is shutting down
by Pim van Pelt 23 Mar '17

23 Mar '17

Colleagues of nanog, In 1999, Jeroen and I started SixXS, a project which aimed to provide IPv6 connectivity to users who wanted to learn about the network protocol and gain experience operating IPv6 networks. Our vision was to facilitate migration to IPv6 in content and access providers. We were able to provide IPv6 to 50’000+ individual users and companies in 140+ countries, using servers hosted at 40+ Internet providers in 30+ countries. We are incredibly proud of what we’ve accomplished together, and how many people have gotten to know all about IPv6 due to our combined efforts. We have completed a retrospective and rationale document, which details our experience developing and operating the SixXS tunnelbroker over the last 18 years. We have worked through our plans with the many dedicated ISPs that have been involved: https://www.sixxs.net/sunset/ We have reached out to users recently, giving them 6 weeks to make alternative plans. We have chosen a somewhat symbolic date of 2017-06-06 to turn down the SixXS service. Our website will remain as a tombstone. Please feel free to pass this along to any group or list you feel would benefit from it, and reach out to <info(a)sixxs.net> or to myself directly <pim(a)ipng.nl> if you have thoughts you’d like to share between now and then. Kindest Regards, Pim van Pelt and Jeroen Massar (SixXS founders) -- Pim van Pelt <pim(a)ipng.nl> PBVP1-RIPE - http://www.ipng.nl/

Google G Suite Email Contact
by Jason Canady 20 Mar '17

20 Mar '17

Is anyone here from Google's G Suite or email department? I recently acquired a brand who's domain is being blocked by Google Mail ("G Suite"). I have followed all of the steps to be compliant (SPF and DKIM), but email is still going into customer's Spam folder at Google. There is not a massive amount of emails sent, just basic communication such as monthly invoices, support tickets, etc. If anyone has a contact, please share it with me on or off list. I would greatly appreciate it. Thank you! Jason Canady Unlimited Net, LLC

BGP Route Reflector - Route Server, Router, etc
by Justin Krejci 20 Mar '17

20 Mar '17

Nanog, I am working on some network designs and am adding some additional routers to a BGP network. I'd like to build a plan of changing all of the existing routers over from full iBGP mesh to something more scalable (ie route reflection). Fortunately, I am also going to be able to decommission some older routers from the network and so shrinking the existing iBGP full mesh is something I am all too happy to spend time and energy on. For the purpose of this thread though, I am not really interested in the route reflector vs confederation discussion. In doing some research[1][2][3][4][5] I see a lot of discussions, config examples, etc on using route reflectors but most suggest picking a router, or more appropriately a set of routers, to become route reflectors within an ASN. I have not found many resources discussing using a non-router box as a route reflector (ie a device not necessarily in the forwarding path of the through traffic). I am thinking things like OpenBGPd and BIRD could make a good route reflector though they are most often discussed in the context of IXPs (ie eBGP sessions). I am wondering if people can point me in the direction to some good resource material on how to select a good BGP route reflector design. Should I just dust off some 7206VXR routers to act as route reflectors? Use a few existing live routers and just add the responsibility of being route reflectors, is there a performance hit? Install and run BIRD on new server hardware? Buy some newer purpose built routers (Cisco, Juniper, Brocade, etc) to act as route reflectors and add them to the iBGP topology? GNS3 running IOS on server hardware? Something else? How many reflectors should be implemented? Two? Four? What are the pros and cons of one design over another? On list or private off list replies would be great; I'd welcome real world experiences (especially any big gotchas or caveats people learned the hard way) as well as just links to previous discussions, PDFs, slideshows, etc. Heck even a good book suggestion that covers this topic would be appreciated.
