So how many is enough? I would think 3 is a minimum to come close to the
reliability/redundancy of OSPF.
My two cents..
BGP beats OSPF in the reliability stakes easily in my experience. I'd
put as little as possible (loopbacks/internal links only) into OSPF.
Two (or more)
BGP route reflectors deployed to reflect the physical topology/area structure
is explicitly redundant in a way that OSPF isn't.
