Building Routing and Switching Playground

I love discovering how stuff works. I love tinkering with computers and cars in particular. This one here, is about Cisco network devices, which are a form of specialized computers. I

I have this virtual lab I can try to put in good use. The following physical topology can be used to create an unlimited variations of L2/L3 labs.

Building The Lab Topology

So, given the physical topology here's the first topology that will be my playground:

Pic1-1: Topology (Vlans)

Now, let's configure layer 2 and IP addressing and start experimenting.
The physical layer (layer 1 from previous post) will be the guide on how to accomplish the above Layer3 connectivity (point-to-point for now).


Initially, I wanted port-channels between the switches but guess what? Ain't working properly (buggy software). Have to settle on this switch-to-switch connectivity for now:

Pic. 1-2: Switch-to-switch Connectivity

Finally, IP addressing and I am good to go.

Pic. 1.3: IP Addressing

Also, below are the Loopback0 IP addresses of all the nodes:

Loopback0 Interface IP Addresses:

R2      10.2.2.2/32
