RE: Newbies Question: Do I really need to sacrifice Prefix-aggregation to do BGP Load-sharing?
by Pirawat WATANAPONGSE 20 Oct '22

20 Oct '22

Dear all, Before all else: thank you all for the lightning-fast responses (even taking the time zone advantage into account). I really, really, really appreciate all your recommendations. Virtually all of you recommend prepending as the first choice. I also get the feeling that you guys consider de-aggregation “distasteful” (at the least) but sometimes unavoidable. I have considered the prepending myself, but dare not implement it yet for the fear that BGP (Human) Community will burn me alive, witch-hunt style, because of the following reasons: 1. I can see from looking glass(es) that my upstreams already practice prepending (some paths) at their level (at least 3 more hops [x4]), supposedly to “balance” their bandwidth. 2. Should I start prepending mine, I might upset their balance, causing them to prepend more, thus starting a “prepend war”. [I imagine that x20+ prepending starts out this way] The way I see it, prepending (or maybe even the whole BGP-Path thing) is a local-optimization problem: it’s only best for someone, not globally. And the Higher-Tiers (Lower Tier-Numbers) will always “engineer” me in the end. Worse yet, I might be out-voted by de-aggregation insider “cultists” anyway. Which forces me to proactively ask you guys questions about ROV-Overlapping and ROV “Hijack Gap” soon, in another posting with separate “Subject:”. Again, Thank you. Cheers, Pirawat. P.S. [Off-Topic] Any comment on the “SCION” System? Any good (I will even take "academically")? [Reference: https://scion-architecture.net/]

Prepending

Hi We have witnessed a lot of prepending in the last days, we got a few internet routes that have 30...200 prepends, did you face the same issue? Regards Mihai

Newbies Question: Do I really need to sacrifice Prefix-aggregation to do BGP Load-sharing? (the case of Multi-homed + Multi-routers + Multi-upstreams)
by Pirawat WATANAPONGSE 19 Oct '22

19 Oct '22

Dear Guru(s), My apologies if these questions have already been asked; in that case, please kindly point me to the answer(s). I hope the following information sufficiently describes my current "context": - Single customer: ourselves - One big IPv4 block + one big IPv6 block - Native Dual-Stack, Non-tunneling - Non-transit (actually, a “multi-homed Stub”) - “All-green” IRR & RPKI registered (based on IRRexplorer report) - Fully-aggregated route announcement (based on CIDR report) - Two (Cisco) gateway routers on our side - Two upstreams (See the following lines), fully cross-connected to our gateways - One (pure) commercial ISP - One academic consortium ISP (who actually uses the above-mentioned commercial ISP as one of its upstreams as well) My current “situation”: - All inbounds “flock” in through the commercial ISP, overflowing the bandwidth; since (my guess) the academic ISP also uses that commercial ISP as its upstream, there is no way for its path to be shorter. Questions: 1. Do I really have to “de-aggregate” the address blocks, so I can do the “manual BGP load-sharing”? I hate to do it because it will increase the global route-table entries, plus there will be IRR & RPKI “hijack gaps” to contend with at my end. 2. If the answer to the above question is definitely “yes”, please point me to the Best-Practice in doing the “manual BGP load-sharing (on Cisco)”. Right now, all I have is: https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/1… Thanks in advance for all the pointers and help given (off mailing-list is also welcome). Best Regards, Pirawat.

For anyone who missed the community meeting this morning at NANOG 86 and wants to know what was covered before the official notes and video are available, here's the notes I took from the meeting this morning. And if you missed Geoff Bennett's talk on how optical networking transformed our world, you definitely need to see it when it gets posted. Absolutely worth the price of admission! Thanks! Matt

Re: AWS Blacklisting?

Is it possible this is a geolocation issue? I'm not sure I've heard of that causing a 403 Forbidden, but I'm also not too familiar with AWS. Justin H.

AWS Blacklisting?
by Justin H. 18 Oct '22

18 Oct '22

I have a customer who's suddenly been getting 403's today on AWS hosted sites. My google-fu seems to be failing me because I can't seem to find any information on who manages that on their side or how to fix the issue. I've sent an email to amzn-noc-contact(a)amazon.com based on ARIN contacts, but it doesn't seem to be a responsive address. Has anyone had to navigate this particular maze before? Thank you, Justin H.

Looking for historical AS1239 Sprintlink on-net site lists, POP lists, etc
by Eric Kuhnke 17 Oct '22

17 Oct '22

If anyone has on-net site/POP lists for AS1239 that are at least 8-10 years old or older, I'm wondering if I could get a copy. Obviously nothing that anybody signed an NDA for, maybe some people out there have some spreadsheets or text files that were shared by Sprint sales persons many years ago. This is related to some information I am gathering to improve documentation of what will apparently become part of Cogent in the Pacific Northwest, with T-Mobile's sale of sprint's wireline business. -Eric

2:45 apple's talk on responsiveness tuesday
by Dave Taht 17 Oct '22

17 Oct '22

It's "fun" to run their new go based responsiveness test on the conference wifi: https://github.com/network-quality/goresponsiveness - especially with two or more people at the same time. Hotel wifi is *even* more fun. in-Bar 5G comparing it (or the new speedtest app which is also measuring roughly the same things) to 4G, oh my! Would love it if more folk tried it and shared data! Also: https://github.com/Zoxc/crusader is shaping up, and has a staggered start test now. And of course, there's always flent. I'm not at this nanog, tho I wish I was. -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-69813666656… Dave Täht CEO, TekLibre, LLC
