Now, our communication is enabled and we are able to communicate from PC_A to PC_B via Router. Now, lets assign IP addresses to the PCs.Ĭlick on PC_A, go to Desktop, then click IP Configuration. See the difference the lights have changed the color from Red to Green.

Now, we have accessed both interfaces one by one and we have assigned IP addresses respectively. Now, commands of the Router CLI mode are as follows. FYI fast ethernet ip address is the gateway address to the PC. Change the status of the interfaces i.e.Step by step , we will have to do the following things. Further, we will go to the router CLI mode and enter the following commands. Similarly, on the PC side we will select fast Ethernet interface. By default, Packet Tracer is installed in the 'Program File' folder of the Windows partition. Now, we will connect them by selecting fast Ethernet interfaces on both ends. The next screen provides an option to customize the installation directory. Here, we will see communication enabled between PCs via Router in Packet Tracer. So, for this we need two PCs, a router ,and two cross over cables to connect them. Important point is that we use cross over cable to connect PC to a router because they both use the same pins for transmission and receiving of data.
