   To see that duplication is happening, on the ovs host, run:  
-  {{{
+{{{
 sudo tcpdump -i <data_interface_name>  [using the data_interface to host2]
 sudo tcpdump -i <data_interface_name>  [using the data_interface to host3]
-  }}}

 You should see traffic from host1 to host2 showing up in the tcpdump window for host3.  As a comparison, you will notice that no traffic shows up in that window when the controller is running the learning switch.
