Summary

In this Lab, I configured a small network consisting of 3 PCs connected to a router. I set up each router port with a different address and then tested to connectivity between PCs to see if there is a working connection.

Useful Commands/Instructions

• The ping command was useful in this lab for testing connectivity between the Laptop and the server, and for seeing ICMP packets in the packet sniffer.
• Cisco Packet Tracer was a useful tool in this lab as it was used in simulating a network and showing the process of how the PCs can communicate over a router.
• A new device that I used that is useful is a sniffer. This device records packets that pass through it and allows you to view the details of the packets that it "sniffs"
• Tip: When connecting PCs directly to a router, use a crossover connection.

Problems I Ran Into

• It took me a little bit to remember that I could add interfaces to the router so I had trouble figuring out how to connect 3 devices to a router with only 2 Fast Ethernet ports, but I eventually remembered that I was able to just add another one.

Tech Journal Questions: Deliverable 6

How did you connect to the edge router?

I had to add an ethernet interface to the router, and then I used crossover cable to connect the PCs to the router. I then set the default gateway on each PC to its corresponding port on the router.

How did you configure the interfaces on your edge router?

I entered the config tab, and for each FA interface that I have a PC connected to, I changed the IP address.

How do you use a sniffer in Packet Tracer?

You use a packet sniffer in Packet Tracer by placing it between two devices that you want to collect traffic from, and then you connect each device that you put the sniffer between to the sniffer.
