Help with sectorizing

Are there any howtos out there on sectorizing some CM9’s on a MT, basically I’ve got 2 routers, both routers have 2 wireless cards in them, 1 is for a backhaul the others are just CM9’s for the sector, basically if someone could help me figure out how I can bridge them together on for example a 10.0.30.0/24 network, I’m not real sure how to bridge wlan1 on router1 with wlan2 and wlan3 on router2, would I set my wlan1 interface to 10.0.30.1/24 then my wlan2 to 10.0.30.2/24 and my wlan3 to 10.0.30.3/24? I read in the documentation that you cannot have 2 different ip addresses in the same network on 2 different interfaces so I guess I would need to use proxy-arp on say wlan3? I’m just really confused I wish there were more example configurations somewhere, if someone could help me out or make me an example configuration I would be appreciative, I don’t know if this should be in general networking or wireless networking, someone help me out, thanks.

Another thing is, you shouldn’t have an ip addresses on any interfaces that are in your bridge correct? Just on the actual bridge itself?
