Packet Tracer labs

In an effort to continue helping CCNA candidates, I’ve taken to doing packet tracer labs on a live stream on YouTube. During the streams I will:

  • Discuss my way through what I am configuring and why
  • Show you how to use show commands to quickly troubleshoot
  • Validate the device configuration as well as it’s operation
    (those are not always the same!)

All the live streams will be available on my YouTube channel. And recordings will be posted here after the fact.

Let’s do Packet Tracer Labs together

In this Packet Tracer lab, we walk through a one of Keith Barker’s lab. We’ll configure VLANs together, verify VLAN paths, look at some Switch commands, and troubleshoot connectivity through a Layer 2 network.

You can download this lab at Keith’s website here.

In this Packet Tracer lab, we walk through another one of Keith Barker’s lab. This one focuses on L3 technologies. We’ll configure some Static NAT’s, and Dynamic PAT’s. We’ll do a little bit of routing. And no lab is complete without a little bit of troubleshooting.

You can download this lab at Keith’s website here.

In this Packet Tracer lab, we yet again walk through another one of Keith Barker’s lab. This one has us in both the L2 and L3 world as we configure VLANS and Trunking on a few switches, and Routing and SVIs on a L3 switch. We explore the concept of L3 switches, and what exactly they are.

You can download this lab at Keith’s website here.

In this Packet Tracer lab, we do yet another one of Keith Barker’s lab. We’ll again explore both L2 and L3 technologies as we configure DHCP, VLANs, EtherChannel, Switching, and Routing. The routing topology uses what is called “Router on a Stick” (ROAS), which simply implies the use of Router Sub-Interfaces.

You can download this lab at Keith’s website here.

Want to see more live stream lab walkthroughs like this? Let me know in the comments below. Send me a link to a packet tracer lab (without violating any copyrights!) and I’ll walk through it on a live stream.

Packet Tracer – Challenges

Beyond walking through labs above, I’ve also put together some Challenges. Labs that I’ve created which I am offering to the community to work through.

The first two I have planned are find the imposter style labs, where you are in charge of a network and must find the bad actors and take them off your network. Enjoy =)

Challenge Lab – Find the Imposter – Layer 2

You’re a network administrator of a somewhat complex L2 network. Your IDS has just given you three MAC addresses on your network which are sending malicious traffic. Your task: Find the malicious hosts, and shutdown the port they are connected to.

You can download this lab here, or watch the Solution walk through video here.

Challenge Lab – Find the Imposter – Layer 3

This will be a similar set up to the L2 challenge lab above, except the topology will be a large L3 network you’ll have to sort your way through. It’s still in development. I’ll update this post when it becomes available.

(under construction!)
