LAB 3-2 - Exploring Broadcast Domains

Objective

Understand broadcast domains on a layer 2 LAN

Goals

• Observe and explain the importance of ARP and layer 2 broadcasts
• Understand the limitations of layer 2 LANs
• Introduce the need for "routing" to connect LANs
• Observe the impact on layer 2 headers (MAC Addresses) as packets cross from one LAN to another

Summary

A lab that had us use our workstation machines instead our VMs and pinged Google's Server and our classmates to capture the ping packets and see what MAC addresses were used. The ping command and Wireshark is becoming familiar as we have used it many a time in previous labs. There were no problems during the lab.

Things to consider:

• Make sure you understand ARP

Worked with in the previous lab 3-1, it gave a introduction on how ARP works.

• Make sure you know how to capture a packet and how to look through network traffic.

This has been done many a time in previous labs using Wireshark to capture packets.
