| ** ANNOUNCEMENT: /r/networking is now secured by WatchGuard™ ** Posted: 31 Mar 2019 03:44 PM PDT After much internal discussion, we are now migrating this subreddit to be secured by WatchGuard. This subreddit will be dedicated entirely for the design, deployment, and maintenance of your WatchGuard solutions. Now we know this won't be an easy change, but let's face it - WatchGuard makes award-winning solutions that are easy to deploy and manage, making enterprise-grade security accessible to any organization regardless of size or expertise. We'll let other vendor posts on here until the end of the day, but starting tomorrow it will be all WatchGuard, all the time! [link] [comments]  |
| Posted: 31 Mar 2019 01:58 AM PDT Hi all, Recently I've started exploring the world of open networking. I couldn't find any documentation on the following questions, so please forgive me if they're too obvious as I'm only making my first steps in this area... 1) I've read that the main advantage BIRD has over other BGP daemons is scalability. Are you aware of any published/publicly accessible benchmarks? 2) Does the network operating system (NOS) really matter, given that I run all routing/switching daemons separately? Does ONL, for example, have any advantages over Ubuntu, RHEL, or OpenSwitch? 3) As far as my exploration went into routing stacks, it seems that there is a variety of solutions - as long as you're using BGP only. The moment you start talking about more advanced features such as EVPN, advanced STP agents, MPLS, etc. your only option is FRR (or stitching a few other solutions). Is there any other solution that gives FRR a fare fight in all areas, or should I just focus on BGP mainly which will enrich my options list? 4) MCLAG (comparable to Cisco's vPC) - are you aware of any open source implementation? From what I saw on the internet, open source networking seems to be more concentrated around IP fabrics and therefore uses ECMP and not MCLAG for load sharing. 5) ONIE vs PXE - is there a good reason to use ONIE? If the whole point is to treat switches as servers, why not use a unified installation platform? And finally - do you have any customer testimony/documentation/blog entries of people who have converted datacenters, WAN infrastructure or even LAN into open source? Cheers. [link] [comments]  |
| Posted: 31 Mar 2019 11:17 AM PDT I am working on a VRF Lite setup for a guest network at a branch office. I am unable to ping from the Branch VRF interface to the Edge or PA VRF interfaces. ping vrf GUEST <IP of Edge VRF int> I am seeing all of the routes in BGP for the VRF. Is this normal?

| Network Automation - Keeping state Posted: 31 Mar 2019 06:57 AM PDT Hi folks, I am trying to automate the process of creating VPN tunnels to AWS when a VPC is deployed. It's been very time consuming for me. Am thinking of the following structure: * A page where the app teams will just input their info (like Account, VPC name, etc) - RBAC is not a problem, and there's a validation process in place. * I have IPAM automation ready with Infoblox through their API - so this is solved too (or at least easily solvable, done it before) * Am coming across this fundamental questions: how do I keep state (i.e. configuration state, you know like in Terraform?) of the routers and firewalls? There are many ways of doing this, but it'd be nice if someone that's done something similar could chime in. Anyone ever done something like this? What tools are you using? To what extent are you automating? [link] [comments]  |
| Unexplained Packet Loss (x-post r/Fortinet) Posted: 31 Mar 2019 03:12 PM PDT Hey, all! I am running out of things to check and thought I would give this a try to see if anyone could think of some other things I could try to track down my issue. Problem: At random times, on random days, my ends users at HQ will loose connectivity to multiple resources in Azure. Some of the traffic is sent IPSEC to a Fortigate-VM in Azure, the rest is Bomgar (also in Azure) via https over internet. All other traffic on the network, including internet, appears to be unphased and with no packet loss. Failures last 10-45 minutes at a time. During this time, neither FG recognizes a tunnel failure. Users connected to Bomgar have their sessions terminated and are unable to re-connect until failure clears. Users outside the HQ building can access the resources with no issue mostly ruling out the Azure side of things. My Network: On HQ Side- Access Layer (Cisco) -> Core (Cisco) -> Fortigate 100D (FW 6.0.4) -> Internet On Azure side - Servers -> Fortigate-VM (FW 6.0.4) -> Internet Completed Troubleshooting Steps: - Confirmed IPSEC configurations match on both sides of tunnel - Set traffic shapers on HQ side (I see dropped packets on the FG side now, however not on the policy for the Azure resources) - Upgraded 100D to 6.0.4 (also had issue on older FW) - Confirmed with service provider that I am not over utilizing circuit - My help desk onsite runs pings to multiple endpoints to see what traffic is loosing packets and confirms there is only loss on traffic to anything living in Azure - Called FG support but there isn't much they can do since we are unable to replicate the issue Has anyone else experienced something similar?

| fast convergence a multi-DMVPN clouds with multi-hub networks Posted: 31 Mar 2019 08:55 AM PDT hello all i have 2 main sites (HUB) and a bout 40 branches(Spokes) they are connected with multiple DMVPN clouds (3) but when in a branch one link goes down i have to wait for NHRP to go down to switch to my second link it takes about 50 seconds to switch witch is a lot how can i fix this issue?

| Automated Network Testing Framework Posted: 30 Mar 2019 10:10 PM PDT I read this great teaser post a few weeks ago... https://packetpushers.net/exploring-robot-framework-for-automated-testing/ ...and it got me scratching my chin about the possibilities of having automated network tests. The article references the robot framework...just wondering if anyone does this currently and any examples or references I could build on. [link] [comments]  |
| Help identifying this fiber optic connector? Posted: 31 Mar 2019 03:28 PM PDT We have a fiber service coming in, which then goes to a Huawei switch (S5300-10P-LI-AC0), and from there to the router. I believe they're just using the Huawei switch as a media converter - there is a single fiber optic coming in to an SFP, then a single copper Ethernet cable that runs from there to the router. I'm trying to identify the type of fiber connector this is? https://i.imgur.com/eE2S0fd.jpg https://i.imgur.com/poNwnqU.jpg https://i.imgur.com/qrbi3jn.jpg Does anybody know? Secondly - the fiber comes in via a hole in the wall, and goes to this box: https://i.imgur.com/5qDQlUp.jpg We need to move the box to a different location - is there a safe way to disconnect the cable from the box, and reattach it afterwards?

| Replacing an individual cable run in a bundle, Need Advice Posted: 30 Mar 2019 04:40 PM PDT I have about 30 workstations out of a 1000 that will not get a network connection. The remote networking people tell me the ports keep going into "err-disabled" mode after they're bounced. They say it's happening because a bad cable. I have replaced all cables, except the runs themselves. I have also replaced the desk/wall port. The only thing left is the cable run from the patch panel to the desk/wall port. These cables are bundled and some probably up to 250 - 300 feet. What is the best way to replace an individual cable in a bundle of them? Some go into the tiled ceiling, some go into the floor. Thanks for any and all help. [link] [comments]  |
| WiFi mesh in uk - which is the best? Posted: 31 Mar 2019 02:49 PM PDT I did a quick search across the group, but didn't get a good answer. Simple question - in the UK which is the best mesh equipment for a large (5 bedroom and large garden 15 meters) house with the BT access at the front of the house - currently using sky with s TP-Link archer 3000 WiFi router - frequent drop outs and blind spots. Thank you [link] [comments]  |
| Posted: 30 Mar 2019 06:45 PM PDT Recently Cisco and Meraki have announced draft 802.11ax (WiFi 6) APs, the MR 45, MR55 and (Catalyst?!) 9115, 9117 APs. My questions to everyone is, what's your experience deploying "pre-standard" APs? Is it worth it? Is it better sticking with tried and tested 802.11ac APs until the full 802.11ax standard is ratified or is there genuine benefit in jumping in feet first with this new gear? For example, someone's deploying a brand new greenfield site next week, what's the best decision? No specific requirements, just want to know people's opinions. [link] [comments]  |
| Using Grid Director Switch as normal switch? Posted: 31 Mar 2019 01:06 PM PDT Hi All, Is it possible to use a Grid director Switch like the Voltaire Grid Director 4036 as a normal switch to connect servers and workstations together? and What is the difference betwen a normal and a grid Director switch?
