Summary

In this lab we created our own network and pinged a machine within this network.

Procedure

Part 1 - Building the Network

Use the Router-PT-Empty. You will need to add three PT-ROUTER-NM-1CFE Modules to the router. To do so, do the following

1. Click on the router and then the physical tab. Use the slider to go all the way to the right and click the power button to turn off the router. The green light should go off.

2. Under modules select the PT-ROUTER-NM-1CFE Module and drag it to the empty slot furthest to the right. Repeat with two more modules placing them in the right most empty slots.

3. Turn the route back on.

This will provide you with three fast ethernet interfaces: 0/0, 1/0 and 2/0.

4. You will need to assign IPs to laptops and router interface. As well as assign default gateways. Device numbers may not match devices you have.

5. Configure the IPs on the router interfaces. You will need 3 different network/IPs

6. Set the appropriate IP's to your workstation's. Workstations IP should be in same network as default gateway.

7. Once all of the interfaces are configured, try pinging from HELLO! laptop to Ping Me laptop.

Part 2: Packet Capture Observation

Using the sniffer inspect packets going from HELLO! to Ping Me and back. Ping both ways

1. Install sniffer between switch and router. Try pinging from HELLO! laptop to Ping Me laptop and observe packet info.

2. Replace switch with a hub and repeat above steps.
