AS8075(Microsoft) Contact
by netops Network Operations 12 Jan '23

12 Jan '23

Hi, Is anybody from AS8075(Microsoft) on the list ? We are trying to establish BGP Public/Exchange Peering Sessions for almost 3 months... Multiple emails sent to peering(a)microsoft.com and inter-x(a)microsoft.com, but never heard back. Later we followed the guide and created all the connections via Azure PowerShell and again, it is in PendingApproval State for more then 1 month. Does everybody has the same experience establishing BGP Peering Sessions with Microsoft ?

Mike, Your original question was: “Given that the project was abandoned six years ago, are there any other efforts with a similar goal (more intelligently placing routes into FIBs of low-FIB capacity devices?” People then, respectfully, tried to clarify your request or explain why placing routes in a low-FIB capacity device isn’t seen as being beneficial. Only now have you added the desire to simply have “more than a default route” in such a router. You can, of course, have more than a default route today - e.g., through local pref and BGP communities for things such as company routes. You haven’t said what you define as “more intelligently”, so perhaps you can more clearly explain the problem you see with the current BGP capabilities via some examples. -mel On Jan 5, 2023, at 8:02 AM, Mike Hammett <nanog(a)ics-il.net> wrote: Then please bless the world with the right way.

I completely agree there are locations in networks that having full DFZ capable routers doesn't make technical or economic sense. But there have long been different products for those different use cases. To perhaps explain my viewpoint better,(and perhaps I didn't properly comprehend the problem you're aiming to solve) : If you are trying to use SDN stuff to shuffle routes on and off a box because you have the wrong sized routers in place, then I would argue you're doing it wrong. If you are trying to use SDN stuff to (as Christopher mentioned) make decisions that are not strictly LPM, and the equipment you have cannot do that, then that's different and entirely reasonable. If the second use case is more of what you were asking, then I apologize for misunderstanding.

Large networks historically have a very poor (IMO) model of gigantic iron in a few locations, which results in sub-optimal routing for the rest of their network between those large POPs. I've heard time and time again that someone buying service from a major network in say New Orleans has a first hop of Dallas or Atlanta. I agree that full-route capable routers need to be in the large, central locations, but it isn't cost effective to have them at every POP, especially if you're a last-mile provider. I'd go into more examples of where it doesn't make sense to have full-route routers everywhere, but I'm afraid that the Internet would then focus on the examples instead of the core idea of intelligently putting routes into the FIBs of low-FIB routers throughout my network. ----- Mike Hammett Intelligent Computing Solutions<http://www.ics-il.com/> [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/ICSIL>[http://www.ics-il.com/images/googleicon.png]<https://plus.google.com/+IntelligentComputingSolutionsDeKalb>[http://www.ics-il.com/images/linkedinicon.png]<https://www.linkedin.com/company/intelligent-computing-solutions>[http://www.ics-il.com/images/twittericon.png]<https://twitter.com/ICSIL> Midwest Internet Exchange<http://www.midwest-ix.com/> [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/mdwestix>[http://www.ics-il.com/images/linkedinicon.png]<https://www.linkedin.com/company/midwest-internet-exchange>[http://www.ics-il.com/images/twittericon.png]<https://twitter.com/mdwestix> The Brothers WISP<http://www.thebrotherswisp.com/> [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/thebrotherswisp>[http://www.ics-il.com/images/youtubeicon.png]<https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg> ________________________________ From: "Tom Beecher" <beecher(a)beecher.cc<mailto:beecher@beecher.cc>> To: "Mike Hammett" <nanog(a)ics-il.net<mailto:nanog@ics-il.net>> Cc: "Mel Beckman" <mel(a)beckman.org<mailto:mel@beckman.org>>, "NANOG" <nanog(a)nanog.org<mailto:nanog@nanog.org>> Sent: Wednesday, January 4, 2023 7:36:58 AM Subject: Re: SDN Internet Router (sir) Disagree that it’s a line in the sand.

The entire Internet routing table consumes at most a few gigabytes when fully structured (and only a few hundred Mbytes stored flat). That’s less memory than your average laptop sports. Even in the worst case scenario, where every network decides to announce only its most specific prefixes, the BGP backbone would temporarily enter an oscillating state that generates a large number of routing updates into the inter-domain routing space. In this case, BGP route damping will quickly suppress the crazies while the backbone stabilizes. Small routers should not be taking full tables, since there is no point to them being in the default free zone. For large routers, neither memory nor CPU speed are an issue. High-speed routers operating in the default-free zone have a critical path in the forwarding decision for each packet: it needs to take less than the inter-packet arrival time for minimum-sized IP packets. This is easy to achieve with today’s hardware. A router line card with an aggregate line rate across all of its point-to-point interfaces of 10Tbps (readily available in today’s gear) can process packets with just a handful of cycles in the FIB Ternary Content Addressable Memory (TCAM) using ASIC-assisted lookups. TCAM is the most expensive component you’re paying for in such a router. It’s not cheap, but backbone routers don’t need to be cheap. They just need to not be memory-constrained. -mel via cell On Jan 3, 2023, at 7:47 AM, Mike Hammett <nanog(a)ics-il.net<mailto:nanog@ics-il.net>> wrote: https://github.com/dbarrosop/sir I came across this over the weekend.
