Watch GNS3 - Router emulation software

GNS3 is a computer program developed by Wiley that emulates the operation of routers and switches to test network simulations. The show stars Don Pezet, a computer network instructor, who helps viewers to understand how to design better network topologies and troubleshoot network problems.

The program serves as a network lab where viewers can put into practice everything they have learned about networking. GNS3 is free and open-source software that is compatible with Windows, Mac OS X, and Linux. It offers rare and advanced functionalities vital for network experts and beginners.

This show offers a hands-on tutorial that helps viewers learn how to use GNS3's features to create custom networks. Viewers will learn the ins and outs of GNS3 from scratch, including how to download and install the software, connecting devices, creating and managing projects, and much more.

The show starts with an emphasis on GNS3's installation process, which is essential to create a network for emulation. Pezet describes how to download GNS3 from the official website and get started with the installation process. Moreover, he explains two versions of software ”GNS3 VM” and ”Local Server” each have their value and situations when to use them.

Then the program focuses on show's main purpose that network simulation of Cisco IOS devices. Pezet explains how to import a Cisco IOS image to the software and start building network scenarios. Viewers will learn how to add routers and switches to topologies, as well as how to configure devices correctly to mimic real network configurations.

Another critical feature in GNS3 that Pezet covers in the program is the use of network automation with Python programming. He shows how to install and configure Python in GNS3 to automate network tasks using libraries like netmiko, napalm, and paramiko.

GNS3 has multiple integrations and extensions available that viewers can use to enhance their experience. Pezet covers integrating different virtual machine operating systems such as Windows, Linux, and macOS. He depicts how to import virtual machines in GNS3 and configure any necessary host-only networks. Moreover, he illustrates GNS3's multitasking and resource allocation functionality.

After a thorough understanding of the software, the show moves on to some practical examples, teaching viewers how to configure specific network scenarios such as BGP, MPLS, VLANs, and OSPF. Besides, the program teaches the importance of security features such as VPN and firewall on the network.

Pezet shares his skillset by demonstrating complex network issues and their solutions using real-life examples, helping viewers understand the concepts better. His approach to explaining and visualizing complex network problems is easy to comprehend and makes learning with GNS3 enjoyable.

Moreover, viewers gain the knowledge about the different types of network protocols, both common and uncommon, and how to use them correctly in their network configurations. The knowledge derived from the show provides a foundational understanding of networking that is essential for anyone beginning their career or striving to expand their skillset to the next level.

In conclusion, The GNS3 show starring Don Pezet is a fantastic resource for anyone seeking to learn how to build and configure networks more efficiently. The show covers various essential topics related to GNS3 and how to use the software correctly. This informative and interactive show is a must-watch for beginners in networking or those who need to brush up their skills.
