1. create a layer 2 (switched) ring, using spanning tree.
- completely independent of openbsd box
2. connect your (dual NIC) openbsd box to 2 separate switches for
redundancy, and add both NICs to a trunk group.
- redundancy of switch, cabling and NICs.

I think probably bridge with RSTP, but I'm not sure how that will
play with vlans (if you use them).
I'd like to do something similar, but I have vlans, and as an
added twist my interconnects are over third-party vlans, and I'm
not especially keen on breaking the third party's switch fabric,
so I haven't risked experimenting much with this yet :)
