Packet Tracer Simple 2 Network - Class Lab

Objectives: Build and observe a Simple Network with 2 Networks

Goals:

Observe the role of the router
Identify the impact of each networks as it's own Broadcast Domain

Lab Steps

Open up Packet Tracer, drag and label the following onto the workspace: Device numbers may not match device you have.

Connections:

1. Connect laptop/server to switches and switches to router (FastEthernet ports on Router) and pay attention to the interfaces you use

2. Network address for Foster is 192.168.3.0/24 and Network address for Skiff is 192.168.1.0/24

3. On CNCS Router

Assign the IP 192.168.3.1 and subnet mask 255.255.255.0 to the Interface connected to the Foster Network
Assign the IP 192.168.1.1 and subnet mask 255.255.255.0 to the Interface connected to the Skiff Network

4. Configure IP's subnet mask and Default Gateway on the Laptop and Server

On the Laptop assign 192.168.3.20, mask 255.255.255.0 and 192.168.3.1 as the Gateway
On the Server assign 192.168.1.40 Mask 255.255.255.0 and 192.168.1.1 as the Gateway

5. Ping server from laptop

Submit: screenshot of successful ping (2 Points)

Traffic Analysis in Packet Tracer

1. Go into "Simulation Mode" in Packet Tracer (stopwatch on lower right)

2. From Laptop - open up "Web Browser" on Laptop Desktop

3. Enter the IP address of server and hit "go"

4. Use Capture/Forward to send to packets hop-by-hop

5. Continue until you see HTTP Packets in the Simulation Panel

6. Review Packet Details of a HTTP Packet in the Simulation Panel

SUBMIT: Screenshot of Details (Inbound or Outbound PDU) of a HTTP packet that includes the Source/Destination MAC, Source/Destination IP Address (2 Points)

Practice Saving Router config

1. Go back to Real-Time mode (clock)

2. From Router: Config Tab: Save NVRAM

3. From Router: Got to "Physical Tab" and use power button to turn off router.

4. Power back on by clicking the button again

5. Use Fast Forward button to get links back

6. Check router to make sure Interface IP's are still there

7. Submit Screenshot of CNCS Router showing IP address on an Interface (2 Points)
