Bridging Wireless Interfaces - Help!

Hi, guys.
I’m a complete newbie at Mikrotik environments, but I’ve been working for a long while at networking.

I give you the following graph I’ve made, and the explanation of what I want to do (if possible) is this:

To place a Routerboard RB600 with its four R52 cards; 3 of them will provide wireless connection to residential clients, and the fourth will be used to build a wireless link ptp to a RB133 which is connected to internet via an ethernet port.

I wish to bridge 3 of the RB600 R52’s (north, west and east) to the RB600 ethernet1 port, to use ether1 as a default gateway of the bridged network, and a static route to and from internet through the RB133.

Is this possible?

How it would be?

Thanks in advance!

This was a good resource when I first started out. It should help you as well.

Also take a look around the wiki for more examples.

I knew the wiki, but the pdf file of the other link is FANTASTIC!

THANKS!!!
