Routing Query

Is this compulsary to have 2 routers one as an AP Router and other as Station client cpe to do routing ?
Can routing is possible with the use of only one router (AP Router) ?

A router does routing on it’s own. If you have two routers, you have two devices that can do routing…

What do you need to set up?

We are usingBandwidth management and Billing server apart from Mikrotik AP Router. Bandwidth management and Billing server is connected to Mikrotik AP Router Via hub.
We have bridge setup(ether+wlan1+wlan2+wlan3 bridged together) in mikrotik AP Router(433ah) Ap-bridge till now...my wireless clients are on 411 mikrotik router As station mode.
Now i want to remove the bridge setup From Ap router and implement Routing in between them.

Bandwidth Management And Billing server details:
Ethernet 1 is connected to hub
