Lab 5-1 - Routing Class Lab

Objective

• Configure and observe a simple routed network.

Goals

• Configure a network
• Observe the Layer 2 header changes as a packet crosses a router
• Recognize the role of the default gateway

Summary

In this lab I made a network with a router, switch, sniffer, and a few PCS, and I had to configure the empty router and switch and give them the appropriate number and type of interfaces. I made sure the network worked by pinging a PC across the router, then I added a sniffer to see what packets were traveling between the router and switch. Some instructions I found to be useful, is when configuring the empty router, switch, and sniffer, turn them off when adding the interfaces and give them time to boot up. A problem I ran into the lab was the sniffer not connecting correctly to the switch and router, what I did wrong, was use the incorrect cable between the two devices. It should crossover for the switch and straight through for the router.

Things to Consider:

• How did you connect to a router?

In order to connect to the router first, you need to add interfaces to it, then with the PCs, I had to use crossover cables since there is no switch between them. With the switch I used a copper straight through since a switch and router are meant to be connected and have similar interfaces.
