+Several InstaGENI racks have hardware switches that support OpenFlow 1.3.  See the [wiki:GeniAggregate GENI Aggregates] to determine which version of OpenFlow a site supports in the `OF Supported` column. 
+
+1. Use the request RSPec https://raw.githubusercontent.com/GENI-NSF/geni-tutorials/master/OpenFlowCtrls/Controllers_all.xml to request a controller.  Once the controller node is up, login to the controller and download a RYU module developed specifically for the InstaGENI OF 1.3 hardware switches.  This module handles the required use of Rule Table ID 100 for HP switches:
+{{{
+cd /tmp/ryu/app
+wget https://raw.githubusercontent.com/GENI-NSF/geni-support/master/Utilities/simple_switch_13_ig.py
+cd /tmp/ryu
+./bin/ryu-manager ryu/app/simple_switch_13_ig.py
+}}}
+
+
+2. After you have selected the OF 1.3 aggregate sites, define a topology that has nodes at different GENI sites using stitched links.  You can pick any site, the key is the link, which must be associated with the controller.
+
+Following is an example for OpenFlow over a stitched link between GPO IG and VT IG: 
+{{{
+  <link client_id="link">
+    <component_manager name="urn:publicid:IDN+instageni.gpolab.bbn.com+authority+cm"/>
+    <component_manager name="urn:publicid:IDN+instageni.arc.vt.edu+authority+cm"/>
+    <interface_ref client_id="ig-gpo:if0"/>
+    <interface_ref client_id="ig-vt:if0"/>
+    <property source_id="ig-gpo:if0" dest_id="ig-vt:if0" />
+    <property source_id="ig-vt:if0" dest_id="ig-gpo:if0" />
+     <emulab:openflow_controller url="tcp:XX.XX.XX.XX:6633" />
+  </link>
+}}}
+
+where: XX.XX.XX.XX is your controller IP address.
