# Testing the basic intent functionality of ONOS
# TODO: Replace the CLI calls with REST API equivalents as they become available.

# TODO: Complete implementation of case 3000, 4000, and 6000 as REST API allows
#           -Currently there is no support in the REST API for Multi to Single and Single to Multi point intents
#            As such, these cases are incomplete and should not be enabled in the .params file
