This video tutorial shows you how to set up and use GNS3 2.2 software on the openSUSE Leap 15 operating system that helps you develop your Cisco network projects.
You can use the GNS3 network simulator program, which allows you to make network designs in a virtual environment on the openSUSE distribution, one of the other popular Linux distributions.
If you are preparing for exams for Cisco or other network technologies, you can experience it by configuring Router, Switch, or Firewall devices.
You can follow this video tutorial or the steps below to install GNS3 2.2 software to make network designs in SUSE distribution.
Step 1: To update the software packages on your SUSE Linux computer, open the terminal and run the sudo zypper update command.
sudo zypper update
Step 2: Run the command below in the terminal to download and install the GNS3 program with Pip3.
sudo zypper install kernel-devel gcc libcap-progs git python3-devel python3-setuptools python3-qt4 python3-qt5 python3-netifaces python3-pip bison flex glibc-static wireshark qemu docker libopenssl-devel
Step 3: After installing the necessary packages on your system, run sudo pip3 install gns3-gui gns3-server to install GNS3.
sudo pip3 install gns3-gui gns3-server
Step 4: After installing GNS3, run the program and add a new IOS device. If you get a dynamips error while adding a router or other device, run the sudo zypper install dynamips command in the terminal and install the software.
sudo zypper install dynamips
Step 5: Create a new project and add the Router you added to the working environment. Additionally, add a Switch and VPCS.
Step 6: After wiring all network devices, turn them on. If you get a uBridge error during this time, run the commands below in the terminal.
sudo zypper install libpcap-devel
cd ~/Downloads
sudo git clone https://github.com/GNS3/ubridge.git
cd ubridge
sudo make
sudo make install
Step 7: If you get an error about the VPCS device in your project when you run the network devices, install VPCS with the sudo zypper install vpcs command.
sudo zypper install vpcs
Step 8: Open the router console and VPCSRoutergn an IP address to each network device, and use the ping command to test the connection.
