Juniper BGP Convergence Time
by Adam Kajtar 31 May '18

31 May '18

Hello: I'm running two Juniper MX104s. Each MX has 1 ISP connected running BGP(full routes). iBGP is running between the routers via a two port 20G lag. When one of the ISPs fails, it can take upwards of 2 minutes for traffic to start flowing correctly. The router has the correct route in the routing table, but it doesn't install it in the forwarding table for the full two mins. I have a few questions if anyone could answer them. - What would a usual convergence time be for this setup? - Is there anything I could do speed this process up? (I tried Multipath) - Any tips and tricks would be much appreciated Thanks in Advance -- Adam Kajtar Systems Administrator City of Wadsworth akajtar(a)wadsworthcity.org ----------------------------------------------------- http://www.wadsworthcity.com Facebook <http://www.facebook.com/cityofwadsworth>* |* Twitter <https://twitter.com/CityOfWadsworth> *|* Instagram <https://www.instagram.com/cityofwadsworth/> *|* YouTube <https://www.youtube.com/channel/UCymlH-AZgvxTaHtgp3-AmDQ>

SIP fax sending software?
by John R. Levine 30 May '18

30 May '18

Can anyone recommend software that sends faxes over SIP? I have plenty of inbound fax to email services, but now and then I need to send a reply and it looks tacky to use one of the free web ones that put an ad on it. I know that if I wanted to pay $15/mo there are lots of lovely services but we're taking about one fax a month, maybe, here. Ideally it'd take a postscript or PDF or Word document and a phone number and fax it to that number. I have Ubuntu, FreeBSD, and MacOS boxes. Any suggestions?

I do not think you adequately understand the economics of the situation. https://www.slideshare.net/InternetSociety/international-bandwidth-and-pric… slide 22, IP transit cost. Your 200mbit/sec link that costs you $300 in hardware is going to cost you $4960/month to actually get IP traffic across, in Nairobi. Yes, that's about $60,000/year. Could *you* afford to "get with the times" if that's what your bandwidth was going to cost you? Please, do a little research on what the real costs are before telling others they need to "simply get with the times." ----------------------------------------- Also, please don't just look at continental countries when researching. Look at the small PICs (Pacific Island Countries). For example, search the posts from Christian on Kiribati on the PICISOC list. The cost is extraordinary and all the ego-flattering bloat rsk speaks (relevant part of the post id below) of in very expensive to download and is nearly impossible to stop. scott * > The problem (part of the problem) is that the people doing these foolish > things are new, ignorant, and privileged: they don't realize that bandwidth > is still an expensive and scarce resource for most of the planet.

Re: BGP Hijack/Sickness with AS4637

Hello, I am the contact for AS16532. We never announced nor are we currently advertising this prefix as we are not a transit AS for anyone. As well, it seems to appear and disappear from AS63956 looking glass. According to that LG, the route changed 6d ago, and is *still currently visible* at this very moment; https://lg.coloau.com.au/ Command: show route 18.29.238.0 protocol bgp table vrf-international.inet.0 active-path vrf-international.inet.0: 696764 destinations, 2288960 routes (696480 active, 0 holddown, 103994 hidden) + = Active Route, - = Last Active, * = Both 18.29.238.0/23 *[BGP/170] 6d 01:06:11, localpref 90, from 103.97.52.2 AS path: 4637 3257 29909 16532 16532 16532 16532 I, validation-state: unverified AS16532 is not announcing this prefix. We have a strict prefix-list that is applied to all sessions. As well, AS29909 is filtering us using our announced AS-SETS/RPSL to avoid us the ability to do anything dumb. And lastly, our announcements are being filtered by AS3257 as we are required to provide them via LOA. There is still something wrong somewhere that is injecting this path, anyone have a LG pointed to AS4637 seeing this prefix announced with AS16532 in the AS path? I doubt that AS29909 bouncing its BGP session with AS3257 (GTT) would change anything, as I am not seeing this prefix in their route-server public(a)route-server.as3257.net-re0> show route 18.29.238.0 protocol bgp active-path inet.0: 691667 destinations, 11752983 routes (691665 active, 1 holddown, 1 hidden) + = Active Route, - = Last Active, * = Both 18.29.0.0/16 *[BGP/170] 3w4d 11:42:33, MED 0, localpref 100, from 213.200.87.23 AS path: 3257 174 3 I, validation-state: unverified > to 141.136.111.13 via xe-1/0/0.0 {master} public(a)route-server.as3257.net-re0> {master} public(a)route-server.as3257.net-re0> show route 18.29.238.0 protocol bgp | find 16532 Pattern not found {master} So whatever is happening, its not at AS16532, AS29909 nor AS3257 that I can find.

MVPN Question - profile 0
by Hari . 30 May '18

30 May '18

Hey - One question on MVPN behavior. Will the PIM JOIN from the customer will be received on all the MVPN members - encapsulated MDT group. ? Can we expect to see the state in all the MDT members? Thought it will be seen only on RPF neighbor? In our scenario, the multicast VRF in PE should be preferring Core2 (thanks to default from core2 with high preference). But still, we are seeing some state created in CORE1. Although the majority is on CORE2. Any thought on why the state created on CORE1 overriding the RPF check? Regards

Yes, that's about $60,000/year. Nonetheless, Safaricom sells entirely usable data plans. A one day 1GB bundle on a prepaid SIM costs about $1, a monthly 1GB costs about $5. They have 4G, it works, I've used it.

A Tier-1 deployed it today. http://www.lightreading.com/data-center/data-center-infrastructure/apstra-d… It can be a lot of things and nothing, it can be just a GUI with some UX built into it, relatively making it easy to configure stuff, and it can be just a bunch of well written automation scripts with all sorts of checks and whistles, it can be just a little bit more analytics on top of that, and it can definitely be something a lot more if done PROPERLY, I hear good things about Apstra but i cant confirm because it can easily be marketing. In my humble opinion, if done properly, the Network Operating System would send telemetry info on any change in the network, and the Intent Based Networking system would consume that, run it by a lot of policies and take automated/guided actions.

BGP Hijack/Sickness with AS4637
by Alain Hebert 29 May '18

29 May '18

Hi, We're looking for a contact, *that works*, to get in touch with AS4637 (Telstra/HK) about some hijacking or router sickness. BGPmon has been reporting an hijack of AS3's subnet 18.29.238.0/23. After being contacted by AS3, we went over the advertisement with AS29909 and AS16532 to be sure. Then we tried getting in touch with AS4637 (Telstra/HK) but it went nowhere at this point. PS: If anyone has better observations that would be greatly appreciated. ----- Context: A few times this month, BGPmon reported an hijack of 18.29.238.0/23 (AS3). For this hijack I see AS4637 (Telstra/HK), AS3257( GTT) AS29909 (MOO) and AS16532 ( (which are peers I know and I'm in contact with). And I'm pretty sure AS3257 (GTT ) is in the same boat as us, as they're not the one advertising those routes to AS4637 AS16532 found it to come from AS4637 as you can see from this ColoAU LG output below ----- https://lg.coloau.com.au/ vrf-international.inet.0: 696533 destinations, 2248101 routes (696249 active, 0 holddown, 103835 hidden) + = Active Route, - = Last Active, * = Both 18.29.238.0/23 *[BGP/170] 1d 19:57:28, localpref 90, from 103.97.52.2 AS path: 4637 3257 29909 16532 16532 16532 16532 I, validation-state: unverified -- ----- Alain Hebert ahebert(a)pubnix.net PubNIX Inc. 50 boul.

Been following the articles on "intent-based" networking from Cisco and other vendors for a couple years now, and I have a basic grasp of the concept of "define your goals/outcomes and automation will make it so", but I do not know the practical applications of it or how you are supposed to convey your "intent". However, $dayjob is a medium-sized enterprise and looking at a potential refresh in the upcoming budget. So... do any of you at ISPs, Cloud Providers, or Enterprises have any hands-on experience with "intent-based" networking products? If so, could you please provide some info on what caused you to look at it, who did you look at, why did you choose whoever you chose, and is it working out for you? If you looked at it very closely and decided not to bother with it, I'd also be interested on your take. At $dayjob we have been adopting automation at the application and workload level, but there hasn't been much need for it at the infrastructure level. However, if we can improve the services we offer while refreshing that infrastructure, it wouldn't hurt - depending on cost of course. Thanks in advance. LF0D
