+11-node 2-bottleneck topology with custom forwarding strategy
+-------------------------------------------------------------
+
+To effectively use the example :ref:`custom strategy <Writing your own custom strategy>`, we need to make sure that FIB entries contain at least two entries.
+In the current version of ndnSIM, this can be accomplished using manual route configuration.
+
+The following example illustrates how the strategy can be used in simulation scenario.
+
+Let us first define a meaningful topology:
