OSPF "hack translation" sought

Gentlepeople - I was wondering what the "translation" of the usual hack on Quagga/JunOS/etc. for OSPF into a proper BIRD config was to allow OSPF to propagate routes to directly connected networks, which are not really part of an OSPF area. In those other systems I would make those interfaces just "passive" members, but BIRD doesn't know "passive interfaces". Making them stubs has obvious other side effects, which is why I just want the "passive" hack to work under BIRD. So what's the equivalent to do this in BIRD? Thanks, Clemens Schrimpe
