"""
This scenario demonstrates the functionality of the IPRoutingHelper. First, the routing helper
calculates and configures routes between all nodes and then calls the `pingAll` command to
demonstrate that all nodes are reachable.
Successful experiments end with: `*** Results: 0% dropped`
To demonstrate the IPRoutingHelper in more complex scenarios, consider starting the experiment with
the Geant-Topology (topologies/geant.conf).
