I have a full bridge network with a little over 300 CPE but i want to change my network to OSPF and route customer per towers, i need the help from someone who has experience, im trying to set it up but cant get it working.
If someone can take a look remotely and help me it will be great!
Its no small task, but very do able. Your design needs to be done proper,
What is your aim?
If you are allocating public IPs to customers (or plan to later) you might also want to consider using the routed network to support backhauls which can be used for central PPPoE etc. .
I don’t want it bridge anymore it has many problems, i started to change routes and ip so it looks more professional!
I feel stuck now with every port in every RB bridged on a single bridge 
I have like 17 RB but i just finished giving new routes to 6 of them including AP’s and CPE’s that are connected to in those 6 routers, btw sorry for my english is not my main!
ok, Well if you can tell me what you are stuck with then i can assist you?
you will have an edge router, and advertise it as such, that router will contain your 0/0 to you internet, (there may be a few of these depending on your network, the rest is easily accomplished by following the ospf manual, you may find that BGP may work better for your network, as BGP is not as sensitive as OSPF when it comes to links dropping and reconnecting, another very powerful solution is the HWMP2+ also a very effective solution.
IT is hard for me to assist by not knowing the layout of your network and so forth.
The Mikroyik Manual is very well documented, an i was able to learn a great deal from it.
