Hey Pau!

Please take your time to respond to this. I understand that this will stall for some time now.

When looking at the p4[1][2] examples I noticed they are in a similar situation. E.g. when building a network of 100 switches, it doesn't say how they are connected (I would make it one big loop).

I think we are in a similar situation and have a need to define topology (without having to rewrite the test).

In the interim I will make sure we can execute our single test properly.
