    203 Note that there is no one-key method to stop `XORP` process, so we have to kill every `XORP`-related process. We can use the command like the one below to kill all `XORP` process at one time.
     203
     204Then Start `XORP` for `router-2`, `router-3` and `router-4` in the same way.
     205
     206If you need to stop `XORP` for some reason, there is no one-key method to stop `XORP` process, so we have to kill every `XORP`-related process. We can use the command like the one below to kill all `XORP` process at one time.

    351 Now, we are ready to add an install script by editing the node property. For each node, click [[Image(GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup:info.jpg)]] to see the node information. By clicking [[Image(GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup:add-service-btn.png)]], we are able to add a service that usually refers to an install script. In this tutorial, we will enter the link ''http://geni-myvini.umkc.gpeni.net/resources/experiments/xorp_autostart.tar.gz'', and the install path is set as ''/local''. By clicking [[Image(GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup:add-exe-serv-btn.png)]], we can add the commend that execute the install script.

By clicking [[Image(GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup:add-service-btn.png)]], we are able to add a service that usually refers to an install script. In this tutorial, we will add an install script called `xorp_autostart.tar.gz`, by entering the link ''http://geni-myvini.umkc.gpeni.net/resources/experiments/xorp_autostart.tar.gz'', and the install path is set as ''/local''. By clicking [[Image(GENIExperimenter/Tutorials/SystematicExprCaseStudy/SmallTopo/DesignSetup:add-exe-serv-btn.png)]], we can add the commend that execute the install script. In the execute box, we enter `/bin/bash /local/xorp_autostart/start-xorp.sh`, and the shell type is `sh`.

    355 Once 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 each virtual router once it is initialized. Setting 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.
     358Once 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.
     359
     360Repeat 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])

    396403This 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.
