Week 2 Guided Practice 1 - VLSM subnetting OL

Introduction to Routing and Switching Lab Week 2 Guided Practice 1 – VLSM Subnetting (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. Scroll down until you see the rack on the left and the table on the right. Go to the routers and click and drag three 4321 router onto the rack. Then click on the switches and drag three 2960 switches onto your rack and place them as show below.

Now turn off your routers and place a NIM-2T and a NIM-Cover into the left and right slots on the router. Turn the router back on. Do the same thing for each router. Next drag four PCs over to your table. There will be a yellow block that appear when your PC is in the proper place. Put two on top of the table on one under the table. You will also place two servers into the rack below the routers and switches. Your finished setup should look like the screen below. You are now ready to continue to Task 1.

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 the second switch and then from the second to the third switch. When you are complete it should look like the diagram below.

Next you will connect the Ethernet side of the console cable to the console port on your R1 router or switch that you are programming. Finally, you will pull a wireless router WRT300N and place it on the top of the first PC 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. Deliverables for Task 1  Screenshot of your wired network in the physical tab.

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 minutes the light will turn green on the switch signifying the router is now talking to the switch successfully. 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.

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.

Sw1 & Sw2id Sw3 You will also need to go back to Switch 2 and add the new VLANs 30 and 40 so it can pass along packets to Sw3

Now program DHCP pools into router 3 so your PCs and pull an IP address from the router. Type the following into the R3 router. Go into each of your PCs and switch them from static to DHCP in the IP configuration tab of your desktop. Finally, you need to program your servers for the networks on router 2. Go into your IP configuration and program the servers.
