Bridged network to OSPF routed network

RouterOS Forwarding Protocols
1

Hello everyone,
I have a bridged network (I’m a WISP) and I think it’s the moment to switch to a routed one using OSPF, because the network is getting bigger.

I started with a bridged network because it’s very simple to understand, but now I’m preparing some redundancy link and it would be great to use OSPF to achieve that.

At the moment I have only a gateway and, bridged with it, all Access Points, connected with the gateway using radio links (MikroTik for most part).
Users have private IPs from DHCP servers (one on each access point), so they aren’t bridged with the rest of the network, only backbone links and access points are bridged.

All users authenticates via PPPoE with their antennas on the access points, and they request authentication to the MikroTik user manager (via RADIUS) that is on the gateway.

How can I migrate to OSPF? Do you have any suggestion?
I would like to understand if it’s possible to configure OSPF without having downtime on the network.

I would like to listen your experience if you already done this!

Thank you!

My network was setup from the start, routed OSPF, which is very good but as a WISP planning for minimum downtime is paramount,

So i would strongly recommend you consider using the services of a professional consultant, pity PM doesn’t work here?

Thank you very much for your time and your suggestion.

May I ask you some example from your network?
