     1= How To Create a Topology using OVS =
     2== Draw your Topology ==
    34This are instructions for Flack to setup your topology.
    910    * In the properties of the controller node press the link tab  (the one that looks like a chain) check the box that says `Routable Control IP (emulab only)`. This will ensure that your node has a public IP.
    11 = Assign IPs =
     12== Assign IPs ==
    1213Once you have drawn your topology you might want to consider assigning IPs to your nodes so that there is less manual steps you need to do after your resources are reserved.
    1314  1. '''Remove IPs from the OVS interfaces'''. The XEN VMs that are going to be OVS switches do not need to have IPs configured in their interfaces so it is probably easier if you remove them at reservation time.
    1617  3. Decide which hosts should be on the same IP subnet and manually assign their IP addresses
    18 = Modify the rspec =
     19== Modify the !RSpec ==
    1920You will need to make some manually modifications to your rspec, so:
    2021  * Save the rspec to a file (`VIew-> Preview Request Document` and Save to File)

    24 = OVS commands once the topology is up =
     25== OVS commands once the topology is up ==
    2627Once your topology is up login to every OVS host in your topology and run the following commands. You will need to run the second command once for every data interface (`eth1, eth2, eth3, `etc). Be careful '''not to add''' the control interface, typically `eth0`.
