10G Router
by sten rulz 04 Sep '13

04 Sep '13

Hello, I am currently looking into a 10G router that will support the below requirements and hopefully not be too costly. Do you know of any models to stay away due to issues or that you would recommend? - 4x+ 10GBE ports - BGPv4/v6 - Small number of RU preferred - Support for 2-4 full routing tables - 2 10GBE ports down to switches - 2 10GBE for up-streams but would prefer more to support IXs. I have been looking into a few options including; Brocade CER 2024C-4X, Broacde MLXE-4 with 10Gx8-X, Juniper MX80, Cumulus Linux, etc. Some quick notes: - 4x 10GBE ports is a bit low for the Brocade CER - Not sure how the CER will handle a few routing tables and 10G+ traffic - The MLX and MX80 is very high costs from what I have seen - The MX80 has 4x 10GBE ports but at less allows an extra 4 via MIC - Decent number of real use case reviews for the MX80 - Possibly use cumulus networks if there are any systems that meet the requirements Thanks Steven

Facebook over IPv6
by Blair Trosper 04 Sep '13

Could someone @ Facebook kindly drop me a line? Your site appears to be riddled with problems on the IPv6 side (whereas it's demonstrably fine on v4). Much of the static JavaScript content being served off your IPv6 CDN is corrupt, missing, or perhaps just outdated. It's preventing the page from doing anything but rendering...it has no interactivity. It's been this way about 24 hours now. Blair

Update on Mailman Outage from the NANOG Communications Committee
by Valerie Wittkop 03 Sep '13

03 Sep '13

Hello All, Just wanted to send you all a quick note regarding the mailman outage NANOG experienced this weekend... A couple of changes made in August on the server resulted in an issue when the new month arrived. We have found the issue, fixed, and now have everything up and running properly again. Lists are working as they should and the web user interface is available should you wish to make any changes to your subscription. We apologize for the interruption, and should you experience any other problems/issues, please let us know by sending a message to admins(a)nanog.org. Cheers, Valerie Wittkop On behalf of the NANOG Communications Committee

Re: TCP Performance
by Nick Olsen 03 Sep '13

I have indeed tried that. And it didn't make any difference. Functionally limiting each router port to is connected microwave links capacity. And queuing the overflow. However the queue never really fills as the traffic rate never goes higher then the allocated bandwidth.

In the scenario where we insert a switch between the radio and the router that does support flow control. Are we not only moving where the overflow is going to occur? Will we not see the router still burst traffic at line rate toward the switch, Which then buffer overflows sending to the radio on account of it receiving pause frames?

Check the radio modem stats to confirm but - if you're seeing lots of drops there you're overflowing the buffers on the radio modem.

Any from O1 alive today?
by Robert Glover 03 Sep '13

03 Sep '13

Dear O1, Your managed modem service appears to not be authenticating users at this time. We have some grumpy dial-up users this morning. Our RADIUS is functioning normally (other services are able to authenticate against it successfully). Your support line (1-888-444-1111) rings fast-busy about 80% of the time I call it this morning (the other 20%, it works fine) Your on-call staff that I paged has yet to respond. Thanks, -Bobby

nanog bug contact
by Randy Bush 02 Sep '13

so i wrote to the old action(a)nanog.org and nanog-action(a)nanog.org and both bounced. i wrote to a friend at amsl and they said "nanog lists are handled by nanog." so here is the public whine. the archive at http://mailman.nanog.org/pipermail/nanog/ seems not to have rolled on 2013.09.01 (gmt, edt, or whatever). and i can not find recent (sept) messages in the archive so i can point to them as a url. randy
