GRE Tunnels

At this point, it is not possible to automatically create links between nodes of the CityLab testbed using the JFed interface. Fixing this issue is at the very top of our TODO list, but because of external factors beyond our control we are currently not able to commit to any particular deadline.

As a workaround it is possible to create these links manually (once the test is running and all the nodes have started). A number of scripts are provided to make this as simple as possible. How these scripts can be used is explained below.
