OK, so I have set things up as recomended, adn indeed all does seem to be
workign as desired. The only remaining issues is the "State" field in
ospfctl show status:

stan@phfw2:stan$ ospfctl show interfaces
Interface   Address            State  HelloTimer Linkstate  Uptime    nc ac
carp1       170.85.106.143/25  DOWN   -          backup     00:00:00   0 0
bge0        10.209.142.153/25  BCKUP  00:00:05   active     00:00:59   2 2

Could some kind soul explain what it means to me?

And thnaks for helping me create another sucesful OpenBSD utilization!
