ah, I think I found what I need - use 'stub yes' in the required interface config in OSPF.

Hi again,

in the quagga configuration you can configure a interface to be passive (participate in the OSPF routing process but prevents that interface from forming neighbor relationships).

I cannot find a configuration parameter for that in the bird OSPF configuration. There is one for RIP and BGP but not for OSPF.

How is this logic solved in bird ?
