Gateway of last resort is 10.1.1.1 to network 0.0.0.0Ĭ 10.0.0.2/32 is directly connected, Loopback0Ĭ 10.1.1.0/24 is directly connected, GigabitEthernet0/0 O - ODR, P - periodic downloaded static route Ia - IS-IS inter area, * - candidate default, U - per-user static route I - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2Į1 - OSPF external type 1, E2 - OSPF external type 2 I am using the OSPF routing protocol in R1 and R2.Ĭodes: C - connected, S - static, R - RIP, M - mobile, B - BGPĭ - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area The cloud in the topology represents the connection with the Ubuntu VM host. I am using the virtual bridge interface, virbr0:192.168.122.1, to connect the two routers R1 and R2 with the VM Ubuntu. The network in GNS3 has two routers with this topology: TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Interfaces in my VM are: docker0: flags=40 NOTE 2: If you get the “dpkg was interrupted” error when you execute the sudo apt upgrade command again, execute the “sudo dpkg –configure -a” command and then you can start the update again.I would like to use monitoring software installed in an Ubuntu VM to manage the network emulated into GNS3, which is also installed in the Ubuntu VM. You can use the sudo kill -9 (Process ID) command in the terminal to terminate the processes using the ID numbers of the conflicting services on your system. NOTE 1: Some services running in the background during the update are blocking the process. If you want to continue with the update immediately, you can use the sudo apt upgrade command. After checking the versions of the installed programs, execute the apt list –upgradable command to see which programs will be upgraded. sudo add-apt-repository ppa:gns3/ppa CopyĪfter executing the relevant command, type the sudo apt-get update command and press Enter to check the current versions of the programs installed on your Ubuntu system. If you want to cancel this process, press the Ctrl + C keys together as you can see in the terminal. To add the repo address of the GNS3 software, enter the root password of your system and then press the Enter key. To add GNS3 to the Repository, type the following command in the terminal and press Enter. Open Terminal by pressing the Ctrl + Alt + T keys together on the Ubuntu desktop. How to Set Up GNS3įollow the steps below to install the Cisco simulator software on your Linux/Ubuntu 22.04 distribution without any problems. Therefore, you will need to install the dependent packages of the program you will install. However, in some cases when you try to install a program on newer versions of Linux, you may find that the required dependent packages need to be installed. In Linux systems, after adding the repo address of a program, you can start the installation and automatically upgrade the next new version of the program when you update your system. The applications on the Ubuntu operating system are usually installed using the terminal. GNS3 is more specific than the Cisco Packet Tracer program, and therefore users who aim to make more professional network designs prefer this simulator program.
