OSPF Route

I am using bird 1.4.0. I configured OSPF and the routes that bird adds
to Linux have a metric of 0. Then I added a static route with the same
network and mask and it has a metric of 1. So now a route that OSPF has
added has preference over a static route but this is not the behavior I
see with quagga or Cisco. With them, the static route has preference.
quagga adds routes with metrics (values 11+) relative to OSPF cost while
Cisco does not add an OSPF route to the FIB if a matching static route
already exists. My expectation, if bird is going to use metric 0, is
that it should not add an OSPF route if a static route already exists
with the same network and mask. Or if it must add an OSPF route, it
should have a metric such that the static route takes precedence. Is it
possible to change this behavior in the config? If so, how?
