  1. In today's experiment you will use resources at the aggregate listed on the worksheet. If you don't have a worksheet use Clemson InstaGENI (aka instageni.clemson.edu)
}}} == 2. Establish the Environment == === 2.1 Pre-work: Install geni-lib === 1. Install the `geni-lib` tool using the [http://geni-lib.readthedocs.org/en/latest/intro/install.html installation instructions] for your operating system. == 3. Obtain Resources == Now that you are a member of a project, you can create a slice and reserve resources. === 3.1 Generate RSpec based on existing smaller topology === a. This experiment already works using this [small topology]. Load (but do not reserve) this topology in your favorite editor to see what it looks like. a. Download this [config file] for the `scaleup` tool distributed with `geni-lib`. a. Open the file using your favorite text editor (`vi` or `emacs`). Replace `X` with the value on your worksheet. If you are doing this outside a tutorial, replace `X` with `1`. a. Run the rspec_gen script on the configuration file: {{{ ./rspec_gen.py -r site.txt }}} a. Look at the generated file using your favorite tool (`less`, `more`, `emacs`, `vi`). a. Can you find each node? Can you find the router node? The host nodes? a. Load the RSpec in your favorite tool (e.g. Jacks, jFed). Find the shared VLAN (it usually looks like a link with only one end point). a. Change the IP address of the shared VLAN to be `10.100.Y.A` where `Y` and `A` are provided on your worksheet. a. Bind the Site to the aggregate listed on your worksheet. a. Save this RSpec. === 3.3 Reserve Topology === a. Reserve the resources a. Wait for the topology to come up. ---- = [.. Introduction] = = [../Execute Next: Execute] =
