GNS3 Fundamentals (Official Course) Part 1

Install gns3 version 2.2 on Windows, configure the GUI and Ubuntu VM, choose a hypervisor (VirtualBox, VMware, ESXi, or Hyper-V), and build a basic topology to test connectivity.

Install the Gns3 GUI on Windows and run the Gns3 VM in VMware Workstation Pro, ensuring matching versions and enabling nested virtualization to build and test topologies.

Learn to legally download Cisco IOS images, import them into GNS3 with the GNS3 VM, and build a topology featuring routers, switches, and Docker containers to test Cisco IOS.

Explore GNS3's emulation options, including dynamips, IOU, and iOS; download the GNS3 VM from GitHub and consider VMware Workstation or VirtualBox, noting that Cisco IOS images must be obtained separately.

Learn to run GNS3 on a server and manage it from a PC, increasing the number of devices you can run.

Identify Gns3 hardware requirements with minimum and recommended specs, including supported OS (Windows 7 64-bit, Mavericks 10.9+, Debian/Ubuntu), cores, virtualization in BIOS, RAM, and storage.

Identify the two device types: emulated devices run a real Cisco iOS image and emulate hardware, while simulated devices mimic functionality and do not run an operating system IOU.

Determine the appropriate iOS image for GNS3 by consulting the docs, noting that dynamips uses older images and iOS images can run in virtual machines for larger topologies.

Explore a range of network operating systems and appliances from multiple vendors, including Cisco iOS, iOS V, IOS XR, NX-OS, Junos, Arista EOS, and FBOSS, and how Gns3 supports them.

Explore how Gns3 emulates Cisco operating systems and other vendors, ios v, ios xr, ios layer two, csr 1000 v, nexus os v, and eos, in topologies and commit changes.

Discover how to legally download Cisco VIRL and iOS images and access them via VIRL and Cisco portals, including understanding license requirements.

Discover the gns3 2.0 architecture by exploring the gui, controller, and compute servers, with rest api access for automating topologies via curl.

gns3 2.0 architecture enables multiple clients to interact with the controller and collaborate on the same project in real time, with qemu iou, dynamips, and kumu for nested virtualization.

Upgrade to Gns3 2.0 introduces a new architecture with features like save as you go, smart packet capture, vpcs clouds and switch templates, and guides upgrades of GUI and VM.

Export and import portable GNS3 2.0 projects across hosts, choose to include base images, name and save projects, then import on Windows and run the same topology.

Explore how GNS3 2.0 profiles apply different settings for home versus office use, switch profiles at startup, and customize layouts and connections for various scenarios.

Explore GNS3 2.0's smart packet capture and capture on any link between any nodes, including iOS devices, with live Wireshark captures and configurable output naming.

Explore GNS3 2.0's colorblind-friendly UI improvements, including a green running indicator and a red square stopped state, plus updated topology symbols for clearer device status.

Learn how GNS3 2.0 lets you connect IOSv, IOSvL2 and other QEMU devices while powered on, a capability not available in earlier versions.

Discover GNS3 2.0's new feature to select where a vpcs runs, choosing between the local server or the GNS3 VM when you drop a device into the topology.

Connect Gns3 devices to the internet using the 2.0 nat node, which requires the Gns3 VM or Linux, and configure dhcp on the router to enable nat.

Explore faster iOS V boot in GNS3 fundamentals part 1, showcasing new iOS V appliance templates, startup-config injection, and performance comparisons with older images.

Integrate a Windows 10 vm running in VMware Fusion with Gns3 on Mac, using the Gns3 vm. Configure two network adapters and ping to verify connectivity.

Learn how Genus 32.0 enables real-time collaboration by connecting multiple clients to a central server, with console session shadowing and synchronized project changes.
