VyOS is a Linux-based network operating system that provides software-based network routing, firewall, and VPN functionality.  Its configuration syntax and command-line interface are loosely derived from Juniper JUNOS as modeled by the XORP project.

First Download Vyos iso image from here

Open VMWARE tool, create a new virtual machine. Select Installer disc image file and select the OS image of vyos and click on next.

Enter your virtual machine name and location. Click next.

Set Ram up to 1 GB for vyos and click to the network adapter

Next, we are choosing our first network adapter. Connect it to the Bridge Adapter and click on close.

Then click on finish.

Now we will check network interfaces using show interfaces command

Now Enter configuration mode by typing “conf” and have a look at the current interfaces:

After you made some changes, you need to enter the “commit” and “save” commands.

Now we will setup network interfaces:

set interfaces ethernet eth0 address dhcp

Now again you need to enter the “commit” and “save” commands. Now we will check network interfaces using run show interfaces command.

Now before we are able to connect to our router with SSH, we will enable SSH In order to do it execute the following commands:

set service ssh 
commit
save

Now before we are able to connect to our router with TELNET, we need to enable that. To do so, issue the following commands
