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.
