| 3 | In this module, we will take a look at the modifications that have to be made in the experiment script to evaluate correct |
| 4 | functionality of both learning switches in the extended topology. This example shows that it is relatively easy to adapt an |
| 5 | existing OEDL script to an extended or slightly modified topology. |
