Configuring virtual wired network devices
Now, let's consider how we can implement our lab network using virtual devices. The logical topology will be exactly the same as the network topology described earlier (implemented on hardware devices) and have the same addressing. The main resources will be deployed in virtual machines on a single-host high-performance computer. For virtualization resources, we will use the free multiplatform software GNS3 and VirtualBox.
To start off, we need a high-performance computer with the correct operating system. In our case, it will be a laptop with an i7 x64 processor, 8 GB RAM, and running operating system Windows 8.1.
