Routing redundancy

I am running a wireless ISP,

I have multiple Mikrotik sytems (15) operating along my backhaul and they are conducting all routing on the network via ospf.

I have 3 bandwidth feeds coming into the network at 3 different locations.

Can anyone give me any pointers as to how I would create redundancy within the network ie. if one bandwidth source goes down all traffic is automatically routed through another source or if a link along the network goes down traffic is automatically routed out another source.

The three different bandwidth feeds are being provided by three different companies and each has its own public IP allocations.

ie

source 1 : 83.200.200.0/24
source 2 : 85.200.200.0/24
source 3 : 87.200.200.0/24

if any further information is required or if I am not being clear enough, just ask!!!

Many thanks in advance.

BGP, OSPF, there are a number of different ways this could be done... you need to be more specific about your network and goals. the 3 ISP's, are they setup with BGP routes for you so that your IP blocks are routable through any of the 3 upstream providers? if not, you're going to have to do some sort of NAT.
