As has been outlined in the design documents, the SDX-to-LC should use an in-band channel for communication. This will likely take the form of a Management VLAN that’s initialized by the various Local Controllers at startup, rather than using out-of-band communication, as has been done so far.
This can be done at any time. Most of the changes are rather isolated, and can be built on top of the existing infrastructure that we already have. Bootstrapping will be per-LC version (e.g., OpenFlow LC vs. a Cisco LC vs. a Corsa REST LC), and must be scriptable as the topology will be different at each location. Ideally, this scripting would come from the manifest file as part of a location definition.
