As images specially created by Cisco for virtualized environments (Cisco VIRL images). You can easily add Virtual Machines (Windows, Linux or others) to your GNS3 topologies. GNS3 is a multi-vendor platform. You can integrate and test multivendor networks.Packet Tracer is not able to do any of that.GNS3 vs. VIRLCisco has released their official lab environment: The Cisco Virtual Internet Routing Lab (VIRL). This is commercial software, and a personal license costs $199 a year. The images that come with Cisco VIRL include Cisco IOSvL2 (advanced switching), IOSv (routing), ASAv (Cisco ASA firewall), and other software such as Nexus OS. This is great news for us as network engineers as we now have access to official Cisco device images which we can use in either GNS3 or Cisco VIRL topologies. GNS3 supports all Cisco VIRL images directly. These are the recommended images to use in GNS3 environments.VIRL limits the number of devices in a topology to 20 devices with the personal edition of the software. GNS3 does not do that. VIRL requires that you authenticate against a licensing server on a regular basis (every few days). GNS3 does not require that.GNS3 does not require an internet connection to verify a license like Cisco VIRL does, and it supports many more device types and devices in a single topology.Want to learn more? Or are you struggling to get GNS3 working?Fortunately, Udemy for Business offers courses that show your IT team all the steps needed to download and configure GNS3 and the various components. See how to sign up for a Udemy for Business subscription to get your IT team up to speed on GNS3. My official GNS3 courses on Udemy were created with Jeremy’s input including GNS3 Fundamentals Official Course Part 1 and GNS3 Fundamentals Official Course Part 2. Life has got

The developers of the GNS3 bring the major changes in architecture of new Version 2.x. Hereby, the step by step installation of the fantastic major release.These are the requirements for the installation:GNS3 Version 2.xInternet ConnectionCisco IOS images (Router, Switch) as per requirements.Installation of GNS3 Version 2.x on Windows 10. Step 1:Download the GNS3 software from Double click on the software and then follow the below installation instructions. You can choose any option as per your requirement.Step 2:In the Setup Wizard we will configure our GNS3. The IOS images which you will run during the configuration of the topology.Here you have a choice where do you want to run your GNS3 and IOS images. If you will get such error message quit from the Setup Wizard and open the Preferences from the Edit tab of GNS3.Under the Binary images sub-tab of General Preferences browse or select the folder where you have kept your IOS images.Now, add the IOS images by clicking on New button in the IOS routers, subtab 'IOS routers' of Dynamips.You can receive warring message in case of invalid IOS images.You can click on OK and take the next steps or select the another appropriate IOS image.For connecting the devices with each other we need to choose the Network adapter at the specific slot, we can also make these changes later.By selecting the correct Idle-PC value, we can prevent the IOS to over use of the CPU processing, and it is really very effective.Apply the changes and run the

There are 3 different methods how you can connect your real switches to your GNS3 routers: Using a breakout switch. Using cheap USB network adapters. Using Quad NIC PCI cards. This article is how you can build your own GNS3 server using Quad NICs, if you are looking for a serious and reliable CCIE lab this is the way to go. I built the breakout switch before which you can see in my other article but the Quad NIC solution seems to be far more stable. Before I continue, if you don’t like reading you can also watch my Youtube video which you can find at the bottom of this article! Equipment List: 1x Codegen 4U-500 19 inch Rack: I like this case because it’s cheap, sturdy and in 19 inch format. If you want you can put this case and the switches in a nice 19 inch rack. 1x Asus P8H67-V Motherboard: I bought this one because it has video onboard, 3 PCI slots and 1 PCI-express slot for my serial ports to connect the switches to. 1x 8GB DDR3 Corsair memory: In the future I want to run virtual machines on this server as well, just for GNS3 it’s overkill. 1x Intel I5 CPU: Same story…for GNS3 a bit too much but if you want to run virtual machines as well it’s nice. 1x Corsair Powersupply: Just because I need one, 500 watt should be sufficient. 3x D-Link DFE 580TX: These are awesome, 4 FastEthernet ports per PCI-card and not too expensive on Ebay. 1x 4-port serial PCI-express card: Very nice card which has 4 serial ports to connect my switches to ( you can also buy 4x USB 2 Serial instead). 2x Cisco 3560 Switch. 2x Cisco 3550 Switch. If you are on a low budget just get cheaper hardware. A core 2 duo can run 12 routers with no problem and you don’t need more than 4GB of memory. I wouldn’t recommend getting other Quad NICs than the D-Link DFE580TX since it’s working right out of the box and not too expensive. You can also use 4x 3550’s but keep in mind the QoS of the 3560 is different and there is no way to practice private vlans. Installing Ubuntu: Installation of Ubuntu was a piece of cake, the D-Link Quad NICs and the serial port PCI-express card are detected and work out of the box, I didn’t have to install any device drivers. If you install GNS3 from the Ubuntu repositories you’ll have GNS3 0.73 which is working fine for me, there are no features in GNS3 0.74 that I need for this CCIE lab. I don’t have a monitor or keyboard connected to this machine so I decided to configure VNC server which is installed by default in Ubuntu, just configure it and you are ready to go. Installing ser2net: Ser2net will make sure you can access your serial ports from the network by telnetting into them, this is what you need to do:
