    56 === C.1.2 Setup Routing in Experiment Topology ===
    57 In more complex topologies routing has to be set up. In our case, this is achieved with the aid of an [[http://emmy9.casa.umass.edu:/GEC15-GIMI-Tutorial/routing.rb OMF experiment script]]. The one we use for this tutorial is shown below.
