Lab 10 3

Summary:

In this lab we used simulation mode to investigate http packets, we also configured a router with two different broadcast domains.

I had no issues completing the lab

Summary of understanding:

Document the use of "Simulation Mode"
- The use of simulation mode is to see packets one hop at a time, and to investigate individual packets as needed
Document how to save configurations on routers
- from an enabled cli you run copy running-config startup-config

Packet Tracer Simple 2 Network - Class Lab

Objectives: Build and observe a Simple Network with 2 Networks

Goals:

Identify the impact of each networks as it's own Broadcast Domain
Examine HTTPS packets from a top-down perspective of the environment.

Lab Steps

Build the following network within Packet Tracer:

Network address for Foster is 192.168.3.0/24 and Network address for Skiff is 192.168.1.0/24. Configure IP addresses, subnet masks, and default gateways for the router interfaces and the PC and server following that network information.
Ping server from laptop

Submit: screenshot of successful ping (2 Points)

Traffic Analysis in Packet Tracer

Go into "Simulation Mode" in Packet Tracer (stopwatch on lower right)
From Laptop - open up "Web Browser" on Laptop Desktop
Enter the IP address of server and hit "go"
Use Capture/Forward to send to packets hop-by-hop
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

Go back to Real-Time mode (clock)
From Router: Config Tab: Save NVRAM
From Router: Got to "Physical Tab" and use power button to turn off router.
Power back on by clicking the button again
Use Fast Forward button to get links back
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)
