I've created a bridge with two internal ports (with IP's set) and set a controller. With netcat I'm able to communicate between the two ports although no controller is running (yet). Why? I was expecting they would be unable to communicate until my controller is running and set things up...
$ sudo ovs-vsctl show

Bridge "br0-loc"
Controller "tcp:127.0.0.1"
fail_mode: secure
Port "a10"

type: internal
