    260260GENI provides the capability of creating diverse, layer two topologies. The topology you have created includes connection at Layer 2.

    319 The two interface that are connected to source and PC-WashDC are mv1.1 and mv1.2 respectively. To figure out which interfaces to bring down, you can inspect the properties of  a link in Flack and see which IP corresponds on each link and find the interface with this IP address.

    331331== 4b. Run Layer 2 Ping ==
    332 From source try to ping `R2`. First we will need to figure out the MAC address of `R2`. We can find the MAC address the same way as we found the interface names in the previous step. The <INTERFACE_NAME> is the interface on `source` that corresponds to the link with `R2`; it is the interface we removed the IP from on the previous step.
     332From source try to ping `R2`. To perform a Layer 2 ping we are going to use a program that is installed on all the nodes (pingPlus) that can be downloaded [http://www.gpolab.bbn.com/local-sw/ here].
     333The command is :
     334{{{
     335sudo /local/tutorial/pingPlus/pingPlus <MAC_ADDRESS> <INTERFACE_NAME> 12345
     336}}}
     337
     338   * <MAC_ADDRESS> is the mac address of the destination host. You can figure out the mac address of `R2` the same way as we found the interface names in the previous step.     
     339   * <INTERFACE_NAME> is the interface on `source` that corresponds to the link with `R2`; it is the interface we removed the IP from on the previous step.

    334341Run :
