7. Save RSpec File and Release Resources

a. Version Control

It is important to save your RSpec at each step. There are three advantages:

  • First, it is convenient to bring up the same topology with the same configuration whenever there is a need.
  • Second, we can add more nodes, links, and even more install scripts to existing RSpec, instead of starting all over again.
  • Third, version control on RSpec is helpful to track errors and debugging issues.

So far, we have created four RSpec files for the 4-router topology. If every thing works properly, we can use Quagga_4node_final rspec as the final version for the 4node topology for future usage.

a. Tear Down Resources

Since we have saved the RSpec file, we can easily bring up the experiment again. Thus, it is not necessary to keep the resources if we do not need to run the experiment any more. We can release the resources by using either GENI Portal or omni.
