Static is simple: just enter an administrative distance (extra argument
at the end) that is higher than OSPF's. Connected has a fixed distance,
as far as I know. But you can get around this by simply putting more
specifics in your IGP. For instance, if the interface has a /24, you let
the router elsewehere announce the two /25s that make up this /24.
