Configure A Router With Packet Tracer Learn Networking. Computer networking professionals getting started with Packet Tracer may find the interface to be flustered. Being a development program, this is only natural. However, learning how to configure a router with Packet Tracer will put professionals on the right track to mastering the program in about half an hour. By this time, you should already have the Packet Tracer download and have it installed on your computer. Open the program and select the router from the lower left hand corner, and drag it into the center of the sandbox screen as seen below. Click for larger pictureWe will be setting up a very basic network that allows two computers to communicate, so the next step is to select end devices from the bottom left hand corner and drag it to the sandbox screen. Do this twice to make two computers appear below the router. Packettracer. The packettracer command can be used in privileged EXEC mode to generate a 5to6 tuple packet against a firewalls current configurations. Cisco Packet Tracer is a software in which you can simulate the complete network by adding and connecting different network devices. Cisco Packet Tracer is. Now select connections from the same bottom left hand corner. When you connect like devicesSuch as a router and computer  you use a crossover cable, so you should select copper cross over cable from the second menu to the immediate right. Click on Router. 0, and connect the cable via Fast. Ethernet. 00 as seen below Now click the PC0 and select Fast. Ethernet. You will notice that although a link is established, it is not functional. You can tell by the red dots that are present on both ends of the connection. Once the router is configured correctly, the red dots will turn green to indicate the devices are able to communicate. Do the same operation to PC1, only this time connect the cable to Fast. Ethernet. 01 since Fast. Ethernet. 00 is already taken by PC0. Rc Cars Demo. Your network should be similar to the one below at this point Configuring The Router In Packet Tracer. A router that is turned off doesnt work very well Click on your router to bring up the configuration menu and verify that it is turned on. When on, there will be a small green light below the switch as seen in the diagram. Next we have to open the Ethernet ports to allow communication. Although they are physically connected, they are in a state that is known as being in administrative shut down. Now click on the CLI tab to access the configuration menu. If youve used the Cisco IOS before, you will notice it looks and acts the same way. Press RETURN to start the session. Type enable to get to privileged mode this gives you more options in configuring the router3. Type config terminal or config t for short to access the configuration menu. Type interface fastethernet. Ethernet. 00. 5. Components that I used to make this computer network in Cisco Packet Tracer 1 Server type ServerPT 10 PCs type PCPT 4 Laptops type LaptopPT. Cisco Packet Tracer 7. Windows. Computer networking professionals getting started with Packet Tracer may find the interface to be flustered. Being a development program, this is only natural. Type ip address 1. IP address and subnet mask to the interface. Type no shutdown to open the interface up for business. Thats it You should now see a message similar to the following LINK 5 CHANGED Interface Fast. Ethernet. 00, changed state to upLINEPROTO 5 UPDOWN Line protocol on Interface Fast. Ethernet. 00, changed state to up. Now we have to do the same thing for fastethernet. If you dont, there still wont be a connection to PC1 Make sure to enter the IP address carefully as seen below 1. Press Ctrl Z to go back to the previous mode. Type interface fastethernet. Type ip address 1. Type no shutdown. At this point our router is configured properly. Univers Bold Italic Font. If you test out a ping, you will notice that the computers still dont communicate, however Configuring The Gateway In Packet Tracer. Our last step is to configure the gateway on each desktop computer. The gateway is the address we assigned to the Ethernet port that the desktop is connected to. It will allow the computer to interface with another network, so our ping wont work without it Click on PC0 to bring up the configuration menu. Under global settings you will find a field for the gateway. Enter the corresponding IP address of the routers interface, which is 1. Then click the Fast. Ethernet tab on the left column to set the actual computers IP address to be on the network. Use 1. 92. 1. 68. IP address, and 2. Do the same thing for PC1, only use 1. IP address, and 2. You can confirm that your network works by sending out a packet of information from PC0 to PC1, and vice versa. Click the packet icon on the right menu as seen below Click on PC0 and then click PC1. On the lower right of the screen you will see a message box that says Successful. If it doesnt, you may have had a syntax error when putting in an IP address or router configuration command.

A real world application of this very network would be to have two computers connected to the Internet, whereas the router would then be connected to your telecommunications company. Or what we would call the cloudMore advanced devices and topologies wont be so easy, but youre now on the right path to becoming qualified for the CCNA certification exam.
