 ** Testbed architecture
 - Now, how does the Community-Lab testbed work? *##*
 - It consists of a set of nodes (managed by CN members) that follow the
   configuration in a set of servers (managed by testbed operators).
 - All components in the testbed become reachable via a dedicated management
-  network implemented as an IPv6 overlay.
+  network implemented as an IPv6 overlay. *##*
 - Then researchers define experiments (the so called slices) in a server.
 - And nodes use a REST API to get those definitions from servers and run
   several of them simultaneously as VMs (the so called slivers).
 - Slivers can access the CN via NAT, natively at the network layer, or in an
   isolated VLAN for routing experiments. *##*
