A cornerstone of all our workshops is ensuring that at least 40% of the time is spent actually configuring equipment. We do this by running a testbed together with our partners on the 6Deploy project. Each of these testbeds consists of 6 routers and they are lots of such identically linked testbeds that can be booked and used for practice or workshops. To book this testbed, go to the 6Deploy global testbed reservation portal.
The diagram below shows both the testbed topology as well as the access topology. Apart from a basic configuration to ensure access from any location, these routers are bereft of any configuration - a true testbed in every sense of the word. Our Lab manual is meant to be used with this testbed.
