No, things changed there as well. Lookup merchant sillicon, and revise this post every 6 months. have you heard of Barefoot networks? The days of ASICs from Cisco are gone and we are glad, we tested the P4 DSL (cisco never got that right with mantel) on Nexus and its wonderful. The asics you speak of are no longer important or valuable because people realized that in many networking planets and galaxies, the asic is reflects the network design, they are related, and specifically for the data center, the clos fabric design won, and that does not require fancy asics. I guess your knowledge is out dated a bit. Cisco itself is using those merchant sillicon ASICs happily. (lookup Chuck's comments on nexus9000, best selling cisco switch ever)...guess it is a good switch, because bright box pushed cisco to do that, and if any one on this list can disagree with me here, i'm up to that challenge. What i have discovered recently is that things happen in following way. Your boss or his boss picks a work culture (no one gets fired for buying IBM/Cisco), that culture (buying the shiny suits) impacts how you do work, it makes you select vendors (the ones that sends me to vegas every year) and not the right network design, you select cisco and you are stuck there for life, because once they tell you how things should work (aka : certificates), things are worse, now every time you make a new network purchase (afraid of new CLI ), you will not be able to look the other way because you just dont know any thing else (and loosing your certificate value). I wish the culture would change to, no one got fired for buying closed but didnt get promoted either. change requires boldness. https://toolr.io/2018/06/18/stop-abusing-the-word-open/ On Wed, Jun 27, 2018 at 9:41 AM, <adamv0025(a)netconsultings.com> wrote: > > Tails Pipes > > Sent: Friday, June 22, 2018 3:00 PM > > > > can you easily answer this question ? why packets are not pushed in > linux ? > > is it because of big switch, cumulus, pica8 ? > > > > can you push packets in linux without writing code to do that ? who is > writing > > that code ? > > > > this is supposedly a community effort, something that older generations > > dont understand. > > > If pure linux as NOS has some legs it'll fly regardless of cisco blessing, > don't worry no single company owns the whole industry. > Also we can argue that this is only about the OS but in reality it's also > the quality of apps running on top and the quality of the underlying HW > that plays a major role. > The quality of BGP app for instance, or the ability of the forwarding ASIC > to deliver the stated pps rate even if multiple features are enabled or > protect high priority traffic even if ASIC is overloaded. > > > Oh and with regards to: > < I am sick of having to learn all the cisco specific terms to all sorts > of different boxes and technologies > I'd recommend you read all the cisco books on networking to get yourself > educated on the topic and to get the difference between SW and HW > forwarding ( -on why packets are not routed in linux) > And while on that I suggest you read all Stanford university lectures on > how routers work too, it'll help you understand why Cisco and Juniper ASICs > are so much more expensive than white-box ASICs. > > adam > > netconsultings.com > ::carrier-class solutions for the telecommunications industry:: > > >

Time to add 2002::/16 to bogon filters?
by Job Snijders 06 Jul '18

06 Jul '18

Dear all, TL;DR: Perhaps it is time to add 2002::/16 to our EBGP bogon filters? It is kind of strange that in the default-free zone (where we don’t announce defaults to each other) - we will propagate what is effectively an IPv4 default-route, in the IPv6 DFZ. IETF has politely abandoned the prefix: https://tools.ietf.org/html/rfc7526 Wes George highlighted operational problems from accepting 2002::/16 on the data-plane slide 6: http://iepg.org/2018-03-18-ietf101/wes.pdf Is there still really any legit reason left to accept, or propagate, 2002::/16 on EBGP sessions in the DFZ? Kind regards, Job

Submarine Cable Status Map Experiment
by Mehmet Akcin 28 Jun '18

28 Jun '18

Hello NANOGers, Today i presented a lighting talk to ask for feedback on the submarine cable status project. I am still trying to work details on how the governance and sustainability of this project should be structured. I know there are more people in the list than those who attend in person to NANOG in Denver hence I want to share my slides here https://pc.nanog.org/static/published/meetings/NANOG73/1749/20180626_Akcin_… There seems to be tremendous amount of interest and support on this experiment. We are working on getting data (Kmz/Kml) from the operators of submarine cable systems so we can build our map and display cable status current demo page is available at https://map.kapany.net If you have ideas you want to share and help this map experiment become a reality, please don't hesitate to contact me directly or join our mailing list. at https://groups.google.com/a/kapany.net/forum/#!forum/subsea I would like to thank Aaron Hughes, Ognian Mitev, NANOG PC, Telegeography , Angola Cables, Alaska Communications and Seaborn Networks for their amazing support so far. ps: please feel free to pass this message to other groups / nogs to get the message to those who are interested. Thank you! Mehmet

Dear nanog members, JPNIC - Japan Network Information Center is now soliciting your input about the situation of website blocking all over the world, especially from the viewpoint of copyright infringement. In order to cope with vicious infringements, the Japanese government is considering countermeasures including the legislation of website blocking, alleging that blocking technologies are already being operated in many countries and regions of the world(*). JPNIC wants to grasp the real situation of the world. We would be grateful if you could answer the survey below by July 10th. https://docs.google.com/forms/d/e/1FAIpQLSfgxaDgDwHbWOv7RNbHYTRbNHQa_HFCPv0… It would be highly appreciated if you could kindly provide us with your input. (*)Background: Japan calls for 'emergency measure’blocking access to websites that pirate manga and anime https://www.japantimes.co.jp/news/2018/04/13/national/japan-calls-emergency… If you have any question about the survey, please feel free to email us at: web-blocking(a)nic.ad.jp All the Best, Akira Shibuya (on behalf of JPNIC secretariat)

Microsoft Express Routes woes...
by Craig 27 Jun '18

27 Jun '18

This is classic....... We have a direct BGP peering session to Microsoft using Express Routes for the public peering session for services like Email, one drive, etc. this uses MS Public. We also have/use MS Azure Public as well as MS Azure Private in place for a few years now. We have had this happen a few times already where one team at MS makes a routing change, and the other team is either not aware of the change, or else doesn't communicate the change properly. So late last night, while a change was being made to a completely different area of our network, they asked that I back out my change due to our entire organization not being able to access share-point online, or MS One drive. I had zero evidence it was our change. further investigation on our border routers, revealed all four (4) of our ISP's were advertising the MS block as a /24 prefix: A:MY_NAME_CHANGED# show router 1053 bgp routes 13.107.136.0/24 ======================================================================== BGP Router ID:10.11.0.29 AS:122 Local AS:122 ======================================================================== Legend - Status codes : u - used, s - suppressed, h - history, d - decayed, * - valid l - leaked, x - stale, > - best, b - backup, p - purge Origin codes : i - IGP, e - EGP, ? - incomplete ======================================================================== BGP IPv4 Routes ======================================================================== Flag Network LocalPref MED Nexthop (Router) Path-Id Label As-Path ------------------------------------------------------------------------------- u*>? 13.107.136.0/24 250 10450 4.49.118.153 None - 3356 8075 8068 ------------------------------------------------------------------------------- Routes : 1 HOWEVER MS Express Routes was advertising this: A:MY_NAME_CHANGED# show router 1053 bgp routes 13.107.136.0/22 ======================================================================== BGP Router ID:10.11.0.29 AS:122 Local AS:122 ======================================================================== Legend - Status codes : u - used, s - suppressed, h - history, d - decayed, * - valid l - leaked, x - stale, > - best, b - backup, p - purge Origin codes : i - IGP, e - EGP, ? - incomplete ======================================================================== BGP IPv4 Routes ======================================================================== Flag Network LocalPref MED Nexthop (Router) Path-Id Label As-Path ------------------------------------------------------------------------------- i 13.107.136.0/22 300 0 157.229.11.66 None - 12076 So another call to MS support and escalations to get this more specific prefix fixed or if Express routes can advertise this more specific vs the /22 block. *Questions:* Has anyone else ran into this with MS if you have a direct peering session to them? Has anyone did an audit on the route table's received from MS over express routes, vs what they receive from their ISP's and noticed the differences? MS needs to seriously think about: Careful coordination of routing changes Policies to prevent specific routes being advertised while larger blocks are advertised over express routes. Anyway I am tired, as I have not had much sleep, any comments on this, would like to hear from you. -Craig
