    * **Note:** if deploying isolation domains, your network blueprint must define at least one external network per isolation domain. see `networks-blueprint.example.yml` for help with configuring your network blueprint.
    * `create-l3-isolation-domains.sh` takes one parameter, a path to your networks blueprint file; here's an example of the script being invoked:
