Router(config-if)#exit Command is used to return in global configuration mode. Router(config-if)#no shutdown Command brings interface up. It is used to influence the metric calculation of EIGRP or any other routing protocol which uses bandwidth parameter in route selection process. We can use any valid rate here.īandwidth works as an influencer. In lab environment we need not to worry about this value.

In real life environment this parameter controls the data flow between serial links and need to be set at service provider’s end. Router(config-if)#ip address 100.0.0.1 255.0.0.0 Command assigns IP address to interface. Router(config)#interface serial 0/0/0 Command is used to enter in interface mode. Router#configure terminal Command is used to enter in global configuration mode.

You might want to download the following free resources related to networking and Virtualization.R1(config-if)#ip address 100.0.0.1 255.0.0.0 In short, GNS3 has everything you to need to setup either a simple or complex network environment, including a switch, a router, a virtual machine etc. What do you need more? Go get it and improve your networking skills. Not just Network devices, you can also add, configure and test Virtual machines (from Oracle VirtualBox or VMWare), Docker containers etc. You can add additional virtual routers from Edit -> Preferences -> IOS routers link. Start configuring your network environment. The console of the selected network device will be opened in a new Terminal window. Again, right click on it and click Console to connect with that device via Terminal. To power on this device, drag it to the workplace, and right click on the device icon. Just click and drag it to the workplace.Īs you in the above screen, we have added c3745 model Cisco router. The list of added network devices will be found. To start it, click on the Routers icon on the left bar. We already have added a virtual network router, right? From here, you can create various virtual network devices and virtual machines, and interconnect them with other and start testing. Review the network device template, and click apply and OK.įinally, Enter the project name and click OK.Ĭongratulations! You have successfully created a new project with a new virtual network device (Router). Since it is just demo purpose I left it blank. It is necessary to prevent IOS to use 100% of your processor or one of its cores. Select the default WIC (WAN interface cards) modules that should be inserted into your router.Įnter the Idle-PC value. Once you selected the image of your choice, click Next.Ĭhoose the name and platform and chassis of your network device (Router in our case).Įnter the RAM size for your virtual network device.Ĭhoose the default network adapters that should be inserted into your device. I do not want to decompress the IOS image, so I selected the option - "No".Ĭlick "Yes" to save the selected image in the default images directory. You can download the IOS images of your choice from the Cisco or any other sites if available. I already have downloaded Cisco 3745 router's IOS image in my home folder. I'd like to add a virtual Cisco router, so I selected the first option.Ĭlick Browse button to choose the IOS image for the virtual router. Next, you need to add the virtual network devices or virtual machines. I would like to run them from my local system, so I selected "Local Server" option. I have tested this on Ubuntu 16.04 LTS desktop.Īt the first launch, you should see the following screen.Ĭhoose a server type to run your network simulations. Once you installed GNS3 on your preferred distro, launch it using the following command from a Terminal: gns3
