CIS225Unit3GradedExcerise1.docxCIS225 – Unit 3 Graded Exercise – Cable/DSL ISP network
In this graded exercise you are creating the second step of your ISP network. Your network will include Cable modems and DSL DSLAM both connected through your network to the Tier1 Internet provider. You will program your routers for RIP protocol dynamic routing.
For this lab you will use your assigned a student number. When you see a blank in an IP address simply, write in your student number.

Task 1 – Setting up the network
You will be creating the network shown below in this lab.
Initially you will need to wire up three routers with serial ports to allow your network to communicate between routers and out to the Internet.
Add a HWIC-2T serial card into the right hand slot on your router.
Connect the routers together from S0/0/0 to S0/0/1 using a Serial DCE cable
Connect from the routers into a switch using a straight through copper cable.
Program your routers as follows. Keep in mind you must configure your point-to-point connections to be in the same network- R1 to R2, R2 to R3 and R1 to R3.

Verify that your routers are connected properly and communicating by pulling a show ip route from each router. Take a screenshot
Deliverables for Task 1
· Screenshot of your working network (Three routers)
· Screenshot show ip route from each router
Task 2 – Installing a DSLAM for DSL users
Now you will be installing a DSLAM for use by your DSL customer.
The DSLAM in packet tracer is found in network devices on the far right side. Click on the cloud and then select PT-Empty from the right side and drag it to your desktop.
Click on the cloud and turn the power off (you may need to scroll to the right). Fill the DSLAM with nine PT-CLOUD-NM-1AM cards placed in all slots except the bottom left. In the bottom left add a PT-CLOUD-NM-1CGE card. This will give you 9 DSL connections for customers and a Gigabit Ethernet port to connect your DSLAM to the network.
Programming your DSLAM
In order for the DSLAM to transfer traffic from the DSL modem to the Ethernet port you must program the DSLAM. Open the config tab and go to the DSL item under the Connections list.
On the right you will see your DSL to Ethernet connections. Click the Add button. You will see this will add the connection from Modem0 to the Ethernet port on the DSLAM.
Select from the drop down menu on the left Modem1 and click add. This will add the second connection from Modem1 to the Ethernet port.
Continue adding ports until all modems have been added to the list. Your DSLAM is now ready to add to your network. Take a screenshot of your completed DSL connection list.
Now connect three Multiuser clouds to your DSLAM using phone cables. Connect the DSLAM cloud to a 2960 switch and connect the switch to Gig0/0 of R1.
Lastly you will connect from your DSL Home Network to one of the Multiuser clouds connected to your DSLAM. Take a screenshot of both ends of the network after you have a successful connection.
Deliverables for Task 2
· Screenshot of your DSL connection list from your DSLAM
· Screenshot of your working networks with DSLAM and multi-user connections
Task 3 – Connections for your cable modem users and Tier1
Cable modems are wired slightly different that DSL users. Cable modems require a one for one modem on your network but in the field there is only a single modem for multiple users which are wired together using coaxial cables with splitters.
For your ISP network you will need to wire a cable modem from each multi-user cloud into the switch for your network.
Connect from your cable modem to the switch using a straight through network cable. There is no other programming required to have your cable modems work with the network.
On your bottom router connect a multi-user cloud to the G0/0 port on your router. This will be the connection from your network to your Tier1 provider.

Task 4 – Connection DSL, Cable, and Tier1 into the network
Now you are going to connect two types of users into your network DSL and cable modem and then connect your ISP network to the Tier1 provider to allow your network users to communicate to the Internet.
Open your packet tracer file for DSL and Cable home networks (Cable_HomeNetwork and DSL_HomeNetwork). Using the multi-user connection from each, connect to your ISP provider.
For your DSL_HomeNetwork you will be connecting to one of the clouds connected to the DSLAM. See images below:
For your Cable_HomeNetwork you will be connecting to one of the clouds connected to one of the cable modems. See images below:
The peer address for your network will be localhost and the peer number should be 38000 but check to make sure these are the correct numbers.
You should be connecting to one of the multi-user clouds on your network so use the peer### from your ISP network.
Connect both of your home networks into your ISP network. Your Home networks should pull a DHCP address from the routers they are attached to on your network. Check your home routers to make sure they have pulled an IP address from the network by checking on the status menu of the wireless router.
If your router does not connect you may need to disconnect and reconnect your connection to the multi-user cloud.
Connect from your third router to the Tier1 multi-user cloud by connecting to the network. For this connection you will be using the Tier1Network_OL file. Connect from one of the clouds on the Tier1Network_OL to the Tier1 cloud connected to R3. See images below:
Verify you can see the Internet by typing show ip route on each of your routers- you should see a route to the 11.1.1.0/24 and 11.2.1.0/24 networks via RIP at the bottom of your routing tables.
R 11.1.1.0/24 [120/2] via 10.50.5.9, 00:00:04, Serial0/0/1
R 11.2.1.0/24 [120/1] via 10.50.5.9, 00:00:04, Serial0/0/1
Take a screenshot of a show ip route from each router. You many need to unplug and plug your cable from R2 to the Tier 1 cloud for these networks to show up in your routing tables. These are the network addresses that reside on the router on the Tier 1 network.
Ping from your R1 router to the Internet by typing ping 11.1.1.10. You many need to unplug and plug your cable from R2 to the Tier 1 cloud again for the ping to work. Take a screenshot.
Go to your PCs on the DSL and Cable networks and pull a web page by opening the web browser and type server.com into the location bar. Take a screenshot.
Deliverables for Task 4
· Screenshot of your working network
· Screenshot of show ip route from each router
· Screenshot of ping from R1 to 11.1.1.10
· Screenshot of web page from each PC
