This is my first tutorial video of Cisco Packet Tracer for beginners. In this video I briefly explain how to use Packet Tracer and draw a network diagram using network devices such as routers, switches, PCs and network cables. This network diagram has three different networks which are 192.168.1.0, 192.168.2.0, and 192.168.3.0. In here I use class C, IP addresses. In my next video I am going to show how to configure Cisco routers using basic Cisco IOS commands.
