    333333Click '''Import''' and select '''Import from file''' from the pull-down list, then select `4node-v1.rspec` from the location where you have just saved to, and confirm it. You will see the four-node topology on your canvas, and each node has been configured to have the custom image.
     
    382382This indicates that we can add custom image and postboot scripts by directly modifying the request RSpec, this is helpful when we have a larger topology.

    403403In the next step, we will add two end hosts to current four-node topology, so now we can delete existing resources from the current slice.

    409 Once we have verified the routing functions for the virtual router, we add end hosts to validate the end-to-end communication.  As the figure shows below, we create the same four-node topology by loading `4node-v3.rspec` in Flack, and create two more VMs as a client and a server, and add two virtual links.  For client and server,  we select regular `Ubuntu 12.04` OS in the node information, so we need to install `iperf` separately. We can also write a script to install `iperf` to the client and server, and the script can be loaded as an install script.

    411 The install scripts for client and server can be downloaded from [http://geni-myvini.umkc.gpeni.net/resources/experiments/install_script.tar.gz here].

In this example, there are only two hosts need iperf installed, so one option is to login to each host, and manually install it by running

     416Or, we can also write a script to install `iperf` to the client and server, load it as an install script by following the same steps as we just did for XORP. The install scripts for client and server can be downloaded from [http://geni-myvini.umkc.gpeni.net/resources/experiments/install_script.tar.gz here]. An sample RSpec with iperf install script and execute command can be downloaded at [http://groups.geni.net/geni/raw-attachment/wiki/GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup/4node-v4.rspec 4node-v4.rspec].
