OSPF and DMZ bridge

I have got an few DMZ bridges between my AP’s

In the bridge there is are 2 Wlan and 1 ethernet, as soon as I enable ospf, it becomes non reacable, then I have to set it back to WDS to access it, is there an easier way of setting up OSPF?

OSPF requires a Layer 2 relationship. When you disable WDS then you no longer have a bridged “layer 2” relationship. If you must use OSPF and cannot use WDS then you will probably want to setup a routed relationship and use an EoIP tunnel but this adds a lot of complication for a routing protocol that can be very simple and powerful.
