May be, but in my case the route is propagated, just without explicit
forwarding address (so the propagating router is used as one, which is
OK). I don't have a proper fix for that, it is a bit tricky problem.
For a workaround it might help to reorder protocols in config file
(OSPF before static, you can check in log file whether OSPF gets iface
notifications before static).
