Why GNS3 vm Download is Made and used
It is possible to access the GNS3-VM in several ways. You can import them into your favourite hypervisor after they have been retrieved.
Client/server architecture is used by GNS3. Its two components are the GNS3 server and the GNS3-all-in-one software.
The gns3 vm download is installed on your local computer and is known as GNS3-all-in-one. Topologies can be constructed and tested using its graphical user interface.
GNS3 is the name of GNS3, the server component. It stores and runs all of the equipment you use for the client segment.
The GNS3 server can be set up in one of three ways.
Install the GNS3 server on the local PC as an application.
Make a virtual machine on the local computer, then install the GNS3 server inside of it.
Create a virtual machine on a different host, and then install the GNS3 server on it.
You can pick any choice, depending on your requirements and machine configuration.
The first option is the simplest. No additional configuration is needed. Use this option if you want to create small networks or only add a few Cisco devices to your network. There is less need for hardware configuration, but fewer devices are supported.
The second choice necessitates the use of a virtual computer and further configuration. If you want to create intricate networks or add a lot of Cisco hardware to your network, you can choose this option. This configuration supports all the devices needed to practise CCNA/CCNP test topics, but it necessitates further hardware configuration. To use the eve ng firepower, you need a laptop or desktop with at least a dual-core processor, 8GB of RAM, and 40GB of free disc space.
The third option is the trickiest to pick and if you want to add devices from different suppliers or create large networks, you can utilise this option. Administrators test their networks using this option.
The virtual devices of GNS3
In GNS3, there are two methods for creating virtual devices. These methods include simulation and emulation. The first method creates a precise virtual duplicate of the device using GNS3. The second method creates a virtual representation of a few selected physical device features and functions using GNS3.
If you choose the first choice, GNS3 will need your IOS image files. IOS image files include an operating system for Cisco hardware. The second choice exempts you from providing GNS3 with any IOS image files. GNS3 immediately installs the necessary operating system on virtual devices that are being emulated.
