    97 Choose '''Save to file''' to export the RSpec. In this tutorial, we assume the file is saved to `4node-v1.rspec`, but you can choose any name as you like. (You can download a sample RSpec for `4node-v1.rspec` at [http://groups.geni.net/geni/raw-attachment/wiki/GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup/4node-v1.rspec here])

    358358Once we added the service and the execute service in Flack, apply the changes and submit the VM reservation request, the OSPF configuration file will be automatically created and the XORP will be started at `router-1` once it is initialized.

    360 Repeat the same procedures for the other three routers (i.e., `router-2`, `router-3`, `router-4`), and then '''submit''' the request. When all resources are ready, '''Save''' the RSpec as `4node-v2.rspec` at this stage, we will load this RSpec in the next step to get the same setup. (You can download a sample RSpec for `4node-v2.rspec` at [http://groups.geni.net/geni/raw-attachment/wiki/GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup/4node-v2.rspec here])

    362362Setting up the install script will automate installation or configuration process at every node's postboot stage, and we do not need to login to every node to run `start-xorp.sh` manually.

    422 After adding the new install script to every node, send the resource reservation request. When all nodes are ready to login,  we save the new modified RSpec as `4node-v3.rspec`. (You can download a sample RSpec for `4node-v3.rspec` at [http://groups.geni.net/geni/raw-attachment/wiki/GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup/4node-v3.rspec here])

    424424In 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.

    447 Or, 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://www.gpolab.bbn.com/exp/sysexpr/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`].
