    699699The Mesoscale deployment can offer different topologies for communicating between hosts. We have provisioned two different subnets in the Mesoscale infrastructure, each using a different VLAN (one using 3715 and the other 3716).
    700700
    701 The two subnets that have been provisioned are '''10.42.144.0/24''' on 3715 and
    702 '''10.42.149.0/24''' on 3716.
     701The two subnets that have been provisioned are '''10.42.144.0/24''' on 3715 and '''10.42.149.0/24''' on 3716.

    704703First of all let's see how we can figure out the IP of the hosts we reserved :
     
    721720   * Figure out the last octet of the IP address of your hosts. The way these MyPLC hosts are setup, is that they have multiple subinterfaces, each configured to be part of a different IP subnet. Almost all subnets in the hosts are in the form of 10.42.Y.0/24. You will notice that for all these subnets, your host has the same last octet.  In the example above all the subinterfaces of eth1, will have an IP address that will end in '''90''' (10.42.147.'''90''', 10.42.148.'''90''')
    722721
    723    * Ping over 3715. After loging in to your hosts ping from host1 to host2.
    724 Assuming that host2 has a last octet of YYY you should:
    725 
     722   * Ping over 3715. After logging in to your hosts, ping from host1 to host2. Assuming that host2 has a last octet of YYY you should:
    726723   {{{
    727724ping 10.42.144.YYY
     
    729726   Notice the RTT on the packets.
    730727
    731    * Ping over 3716. After loging in to your hosts ping from one host2 to host1.
    732 Assuming that host1 has XXX as it's last octet you should ping
    733 
     728   * Ping over 3716. After logging in to your hosts, ping from one host2 to host1. Assuming that host1 has XXX as it's last octet you should ping
    734729   {{{
    735730ping 10.42.149.XXX
    736731   }}}
    737    Notice the RTT on the packets and compare it with the above ping.
     732   * Notice the RTT on the packets and compare it with the above ping.

    739734= III. Run a Layer 2 Experiment =
    740735
    741 The mesoscale GENI resources are connected on Layer 2, which enables Layer 2, i.e. non-IP experiments. In this exercise we are going
    742 to run a layer 2 ping program, where we are going to send raw Ethernet frames of a custom Ethernet type to a server and receive a reply.
    743 Currently MyPLC only supports IP experiments, so we will use our ProtoGENI host which we have reserved in the beginning.
