    * Run the Layer 2 Ping
-   We have pre-configured the network to forward along Layer2 packets of Ethernet type '10131', so let's try pinging with that. 
-   The software that is going to send Layer 2 pings, is called pingPlus. Change to the pingPlus directory :
-   {{{
-   cd pingPlus
-   }}}
-   There is a server running at a host with mac address '00:15:17:d4:64:c2'. Run the client :
-   {{{

    Send a stream of packets, by specifying the number of packets as the last parameter :
    {{{

 Congratulations you ran a Layer two experiment across the country!
