I have a similar deployment requirement (lots and lots of interfaces)
which don't need ospf running on them, two default routes learnt,
routes for the interfaces advertised.
As all my routes are directly connected, my plan was simply to
redistribute into OSPF. However, the issue here is that some of the
routes are interface routes (i.e. routed to the interface rather
than the interface being numbered). For reasons I don't fully
understand, a numbered interface can form part of an OSPF
stubby area, but an interface route can't (wrong LSA type).
In the absence of NSSA, is changing the LSA type of redistributed
connected and interface routes an option? (this also has the
advantage I don't need to reconfigure bird when adding/removing
