    That should be enough.

    Even FWaaS APIs are supported in ODL now? If so, I guess ODL is even
ready to do (basic) 'redirect' action once it is implemented on the mapping
driver then.

    And no, you should not need any other APIs.

different from before, the magic happens in the mapping driver layer.

    It doesn't. That said, I fully expect the ODL Neutron handling layer to
support GBP APIs in the (near) future. When that happens, instead of using
the mapping driver, you will have an additional choice of using the ODL GBP
driver.

Hope it helps,
