Settings for physical_interface_mappings
I am confused by the physical_interface_mappings line in the linuxbridge_agent.ini file.
If my Compute node have no direct connection to the provider network (i.e. all outbound traffic must be proxied through the controller/network node via an overlay network), should I just comment out the "physical_interface_mappings =" line on the compute node, then set "physical_interface_mappings = provider:eth2" on the Controller/Network node (assuming eth2 is connected to provider network)?
