BUGFIX IP-Routing helper did not work for large topologies
The initial version of the IP routing helper had issues with larger
topologies, especially when multiple paths between nodes are possible.
This fix ensures, that the same route between two nodes are
installed in both directions. This leads to a 100% reachability of nodes
in larger scenarios.

+"""
+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).
