Re: route for linx.net in Level3?

Actually, that may not be the case, and probably *should* not be the case. Here's why, in a nutshell: If two regional ISPs on either side of the planet, point default to the same Global ISP, even if they do not peer with that ISP, by using the IX next-hop at IX A (for ISP A), and IX B (for ISP B), then the Global ISP is now giving free on-net transit to A and B. So, it turns out that pretty much the only way to prevent this at a routing level, is to not carry IXP networks (in IGP or IBGP), but rather to do next-hop-self. The other way is to filter at a packet level on ingress, based on Layer 2 information, which on many kinds of IX-capable hardware, is actually impossible. So, when it comes to IXPs: Next-Hop-Self. (BCP 38 actually doesn't even enter into it, oddly enough.) Brian

Having trouble reaching route-views.linx.routeviews.org from AS3582.

I don't know how they calculate bandwidth, but I was surprised that their system gave such wrong results under what were effectively lab conditions. ------------------------------------------ It'd be nice to know if NDT was not accurate as well. Anyone tested it? scott

Given we are moving into the hurricanes season in a few months, I was wondering if this is now an accepted standard. I haven't seen many updates - it appears to be complete as is. Thanks,

MikroTik + EAP-TLS + Non-Channel 1 / Apple iOS issues
by Thomas York 03 Apr '13

03 Apr '13

I know a few of you guys are using MikroTik offerings in the enterprise, so I hope to pick your brain(s). I have many, many RB433UAH's deployed worldwide as simple WAPs. I've been looking to move to 802.1x EAP-TLS via an external FreeRadius server. I have our HP Procurves using the FreeRadius server without issue. Infact, the only devices that seem to have issues are the MikroTik devices. For one, only channel 1 seems to work with 802.1x. If I change the channel to ANYTHING else, clients refuse to auth. Secondly, newer iOS devices (iOS 5 and newer, I believe) refuse to auth entirely. I have an older iPod touch that is on iOS4 that can authenticate on channel 1. Have any of you guys seen issues like this? Thanks. -- Thomas York

Hi all, As advised a month or so ago, the following public comment period is open: http://www.icann.org/en/news/public-comment/root-zone-consultation-08mar13-… We have received a small number of responses which are accessible from that page. The topic at hand and the specific questions that have been asked as part of the consultation are important ones; the decisions taken will have operational consequences to any user of the Internet who validates DNS responses with DNSSEC. If you have experience, opinions or expertise to contribute, it would be greatly appreciated. The window for being able to submit comments closes on 12 April 2013 at 23:59 UTC. Many thanks, Joe

------------------------ You might want to consider putting up a speedtest server internal to your network. I know there is a fee but well worth it I believe. You will ------------------------ I would consider NDT as well: www.internet2.edu/performance/ndt Last I checked, about 3 years ago, speedtest sent only latin text in large packets. NDT tests much more. The customers just use a web browser and the only caveat is they need to have Java working. Here's one to get a feeling of what your customers will see: http://ndt.anl.gov:7123 scott
