Router configuration(making the world go round).
This is a network design I created using Cisco Packet Tracer. I designed it using 8 routers,10 switches,PCs, etc. Each department having a Sever which issues the IP addresses to the PCs through DHCP and the routers communicating using EIGRP.
With Cisco Packet Tracer you can create so many network design. All you need to know is how your IP addresses are being assigned and also know the right tools to pick. look at the picture below to see your configuration code/commands which is done in the CLI (command line interface) of your router.
