You could even do ECMP if needed. Once the ospf adjacency is setup (and assuming its a DR or BDR) it will route everything out that interface even without a default gateway. OSPF will populate the FreeBSD routing table with the appropriate information. For redundancy, if the link goes down it will automatically fail over and if there's a software problem or similar on the other end the ospf timeouts should kick in and start routing via the other DR or through the BDR.
