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.

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. Deliverables for Task 3 · Screenshot of your working network 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.

Designing a Cable and DSL ISP Network Using Packet Tracer

Introduction

In this guide, we will walk through the process of setting up a simulated Cable/DSL Internet Service Provider (ISP) network using Cisco Packet Tracer. This guide aligns with the CIS225 Unit 3 Graded Exercise and includes key tasks such as configuring routers, implementing dynamic routing with RIP, and successfully integrating a Digital Subscriber Line Access Multiplexer (DSLAM) with cable modem connections. We’ll ensure the network is functioning correctly and provide screenshots of the configurations and functionalities at each stage.

Task 1: Setting Up the Network

To begin, we need to create and configure a network meeting the specifications outlined in the exercise. This includes configuring three routers (R1, R2, and R3) connected via serial connections, and initializing their respective interfaces and IP configurations.
1. Router Configuration:
- R1:
- G0/0: `10.___.2.1/24`
- S0/0/0: `10.___.5.1/30` (Clock rate: 500000)
- S0/0/1: `10.___.5.10/30`
- R2:
- G0/0: `10.___.3.1/24`
- S0/0/0: `10.___.5.5/30` (Clock rate: 500000)
- S0/0/1: `10.___.5.2/30`
- R3:
- G0/0: `11.2.1.___/24`
- S0/0/0: `10.___.5.9/30` (Clock rate: 500000)
- S0/0/1: `10.___.5.6/30`
The configuration commands for each router would be as follows:
```bash
R1# configure terminal
R1(config)# interface G0/0
R1(config-if)# ip address 10.___.2.1 255.255.255.0
...
```
Similarly, for R2 and R3, you would follow the same structure ensuring to replace the IP addresses accordingly.
2. Dynamic Routing Configuration:
Each router will have RIP version 2 configured as follows:
```bash
R1(config)# router rip
R1(config-router)# version 2
R1(config-router)# no auto-summary
R1(config-router)# network 10.0.0.0
```

Deliverables for Task 1:

- Screenshot of the network showing all three routers with their interconnections.
- Screenshot displaying the output of the `show ip route` command from each router.

Task 2: Installing a DSLAM for DSL Users

Next, we will set up a DSLAM to accommodate DSL users. A DSLAM is essential for aggregating multiple DSL connections into one Ethernet connection for transmission to the broader ISP network.
1. DSLAM Configuration:
- Open Packet Tracer and add a DSLAM device to the workspace.
- Add nine PT-CLOUD-NM-1AM cards and one PT-CLOUD-NM-1CGE card.
- After arrangement, ensure that the DSL connections to the Ethernet port are established by selecting modem entries from the configuration interface.
2. Connect the DSLAM to the Network:
- Connect the DSLAM to R1 using a Gigabit Ethernet cable.

Deliverables for Task 2:

- Screenshot showing the DSL connection list from the DSLAM.
- Screenshot showcasing the network with the DSLAM setup.

Task 3: Connections for Cable Modem Users and Tier1 Provider

In configuring the cable modem connections, we will ensure proper network layout and connection procedures.
1. Cable Modem Setup:
- For each multi-user cloud, connect a cable modem to the switch using straight-through Ethernet cables.
- The Tier1 connection will be made to R3’s G0/0 interface.

Deliverables for Task 3:

- Screenshot indicating the completed cable modem setups and connections.

Task 4: Full Network Integration and Testing

Finally, we will establish thorough connections between both DSL and cable modem users and the Tier1 provider, culminating in internet access.
1. Connecting Networks:
- Connect the DSL home network through the DSLAM and the cable home network via the cable modem.
- Use the correct peer settings as specified (e.g., localhost, peer number 38000).
2. Network Testing:
- Execute the `show ip route` command on each router to verify all routes, particularly for 11.1.1.0/24 and 11.2.1.0/24.
- Ping the Tier1 address (`11.1.1.10`) from R1 and confirm connectivity.
- Finally, ensure each PC can access the internet by testing webpage access (e.g., www.server.com).

Deliverables for Task 4:

- Screenshots of the overall network layout.
- Output of `show ip route` from each router.
- Successful ping results from R1 to `11.1.1.10`.
- Successful webpage retrieval from each connected PC.

Conclusion

Through this exercise, we have established a functional ISP network featuring both Cable and DSL connections that leverage RIP for dynamic routing. The successful configuration of routers, the integration of a DSLAM, and connections to the Tier1 provider allow seamless internet access for end-users.
