     89#!html
     90The goal of this exercise is to setup the routing as indicated in <a href="#IPv4RoutingAssignment">Figure 1</a>; i.e.  packets from A sent to IP address 192.168.2.12 on node C should be routed via node B. In order to create this routing behavior you will need to modify the routing tables in your nodes using the linux

     93             <ol>
     94              <li> <b>What happens when you traceroute from A to IP address 192.168.2.12 before you setup the static routes? Why? </b> <br/>Include the output of the traceroute in your writeup</li>
     95              <li> <b>Setup the routing from A to 192.68.2.12 so that it goes through B. Was it enough to just modify the routing tables? What else  did you need to change in order for the traffic to flow? Ensure that you have connectivity by running a ping from A to 192.168.2.12</b> <br/>In your writeup include all the commands you ran and a screenshot of the routing configuration</li>

     102==== 5.2.1 Send IP traffic ====
    88103The first simple experiment that we will run is to verify the IP connectivity between our hosts.

    130 === 5.2 Install and use `iperf` ===
     145==== 5.2.2 Install and use `iperf` ====
    131146    a. Install the `iperf` software on both nodes:
    132147    appropriate command below.
     
    164179    e. Type `CTRL-C` on the server node to stop the `iperf` server.

     181==== 5.2.3 Bring down the server's data interface ====
    167182
    168183    a. ExoGENI nodes run a service called "neuca" that managed network interfaces on the node.  To manually adjust the IP address, we must first disable neuca on both nodes.
