Introduction to Routing and Switching Lab Week 3 Guided Practice 2 – IPv6 (OL) In this guided practice, you will be setting up and programming three routers and three switches using Packet Tracer. In Packet Tracer, you will need to switch to the physical tab (at the top left of the screen) and then drill down to Home city, corporate office, and main wiring closet. You will be programming the following network in the physical tab of Packet Tracer. Your finished setup should look like the screen below.
Task 1 – Wiring your network Your network should have three routers, three switches, two severs and four PCs, which we are going to wire together into a network. We will also connect the first PC into the console ports of the routers and switches and program a hostname onto each. First, we will wire the routers together using serial (HSSI) cables. This allows your routers to send packets between each network and will allow the local area networks to connect together in a wide area network.
Using serial DCE cable from the connections list plug the DCE side of the cable into the left side of the serial card on the router. Go to the second router and plug the other side of the cable to the right side of that serial card. Do the same thing from router two to router three.

Finally, plug from the left side of router 3 back to the right side of router 1.
This will give you a loop through each of your routers and will allow the network to keep working even if one of your serial circuits fails. Next, we will connect a straight through Ethernet cable from the second router’s port G0/0/0 to the top switch. The routers have three ports in the middle of the system which are labeled G0/0/0 and G0/0/1. These are the two programmable gigabit Ethernet ports, which you will be using to build your LAN network. The third port, on the right, is for fiber optics and requires a plug-in module to work. Plug your Ethernet cable into the bottom port labeled G0/0/0. On your switch, there are 24 Ethernet ports and two gigabit Ethernet ports on the right-hand side. We’re going to plug the other end of our Ethernet cable into the first Gigabit port on the right side. Next you are going to wire from the third router into switches 2 and 3. When you are complete it should look like the diagram below.
Wire up each of your PCs into the switches as shown in the table below. System Switch Port Server 1 Sw1 F0/1 Server 2 Sw1 F0/12 PC1 Sw2 F0/1 PC2 Sw2 F0/12 PC3 Sw3 F0/1 PC4 Sw3 F0/12 Now run a straight through Ethernet cable from your first router to the “CSU-DSU” on the second Internet rack. You will notice this connection goes “out of the building” in your network. Now you are going to wire from your console port on your router to the serial port (RS232) port on your PC. Locate the serial port on your PC. Plug the cable that looks like the one on the right into the serial port.

Next you will connect the Ethernet side of the console cable to the console port on your router. Finally, you will pull a wireless AP-PT-AC and place it on the top of the rack as shown below. Wire your wireless router to the G0/0/1 port on the top router by connecting from the Internet port on the wireless router to the G0/0/1 port on R1. Drag a smartphone onto the top of PC2.
Your network should now be wired and ready to be programmed.

Task 2 – Setting up your network We are going to use the console cable you connected from your router to the PC to program the router. First, we need to connect to the router. Open the PC, go to Desktop, and click on terminal. Click on the OK button.
You should now see information coming to you from the router. If you see the following screen, it means your router has not yet been programmed. Simply type no and press the enter key. The router will now drop you out to a user mode command prompt which is indicated by a > after the name of the router. If there is no programming on your system, it will show up as Router>. Otherwise, it will show up with the name of the router and a > character. Type the command enable at the prompt to drop into privileged mode so you can program the router. This mode is indicated by a # symbol after the router name. You are now going to program the router names so they will reflect your student number and R1 through R3. From your command prompt, type configure terminal which will drop you into configuration mode.
Now change the name of your router by typing hostname <studentID>-R1, which will change the name on your system. Type the command exit to switch back out of configuration mode back to privileged mode. Type an enter key to bring up the privileged mode prompt. Do the same for the other two routers with the names <studentID>-R2 and <studentID>-R3 . Notice that now your system name has been changed to the new router name you typed in. Do the same for each of your other routers and switches by moving the console cable, reopening the terminal window, and changing the name of the routers and switches. Or you can wire a console cable from each of your PCs into a different router or switch (this can get confusing though so be careful). Finally, we’re going to turn on the G0/0/0, G0/0/1, S0/1/0, and S0/1/1 ports, so we get green lights from the routers and switches. Open your terminals and type the following commands on each router. You will see the light on the router will turn green, and the light on the switch will turn orange. After a few seconds the light will turn green on the switch signifying the router is now talking to the switch successfully. ena

Change to your switch console port (it is on the back of the switch) and open your terminal, the same way you did for the router. You will need to right click on the switch and select inspect rear and connect the cable to the rear console port. Go into your terminal and type configure terminal again. Go into your PC and open a terminal which is now connected to your switch. Press the enter key to “wake up” your switch. You should now see the command prompt. Type enable just the way you did on your router, and it should switch to privileged mode on your switch. You are now going to program the switch name so it will reflect your student number and Sw1. From your command prompt, type configure terminal, which will drop you into configuration mode.
Configure each of the other switches with their hostname. Your network is now wired and ready to be programmed to communicate. Deliverables for Task 2 • Screenshot of each of your renamed routers (3 screenshots) • Screenshot of each renamed switches (3 screenshots)

Task 3 – Programming your network You will now be setting up your network to talk locally on the LAN and over the Internet using the connection to the CSU-DSU you connected in the last task. Below is the table for all LAN network connections.
Any time you see a ___ replace it on the table with your student number. System Port Connect To IPv6 Address <studentID>-R1 G0/0/0 CSU-DSU 2001:DB8:11:50::1/64 G0/0/1 AP 2001:DB8:___:1::1/64 Se0/1/0 R2 FD00:0:___:9::1/64 Se0/1/1 R3 FD00:0:___:11::2/64 <studentID>-R2 G0/0/0.1 0 Sw1 2001:DB8:___:3::1/64 G0/0/0.2 0 Sw1 2001:DB8:___:4::1/64 Se0/1/0 R3 FD00:0:___:10::1/64 Se0/1/1 R1 FD00:0:___:9::2/64 <studentID>-R3 G0/0/0.1 0 Sw2 2001:DB8:___:5::1/64 G0/0/0.2 0 Sw2 2001:DB8:___:6::1/64 G0/0/0.3 0 Sw2 2001:DB8:___:7::1/64 G0/0/0.4 0 Sw2 2001:DB8:___:8::1/64 Se0/1/0 R1 FD00:0:___:11::1/64 Se0/1/1 R2 FD00:0:___:10::2/64 Program each of the interfaces on the routers as shown above.

Answer the question about the ping - Was it successful? Why or why not? The ping was not successful because the opsf was not setup on the routers yet and the devices are plugged into different switches.

Task 4 – Set up OSPFv3 Routing OSPFv3 routing protocol is set up slightly different than in IPv4. First you need to give your router an ID number so it can communicate with all the other routers on your network. This is done by typing: Your router ID for router 2 will be 2.2.2.2 and router 3 will be 3.3.3.3 Now you must add OSPF to each of the interfaces on each router. This is done by typing the following statements: R1 Notice that all the serial interfaces are area 0 and the outside interface to the Internet is also area 0. R2
