    208208Now try to ping again from VMUT. The output should look like :

     223Congrats you were able to run a multihop IP experiment.
     224
    212225= 3. Sending Layer 2 traffic =
    213 == 3a. Login to VM@Utah ==
     226GENI provides the capability of creating diverse, layer two topologies. The topology you have created includes connection at Layer 2.
     227The layer two part of your topology looks like this; the actual info of your topology might be different.
     228
     229In this exercise we are going to send layer 2 traffic between the hosts of our topology.
     230
     231== 3a. Bring Down IP at PCUT ==
     232First of all lets bring down the IP configuration from our hosts. At the terminal  of PCUT first run ifconfig to figure out which are the dataplane interfaces. Run :
     233{{{
     234/sbin/ifconfig
     235}}}
     236
     237The output should look like :
