As far as I remember, if you set the interface in a filter, than the gw is

Yep, checked the documentation, and here it is:

https://bird.network.cz/?get_doc&v=20&f=bird-5.html#ss5.5

  string ifname

     Name of the outgoing interface. Sink routes (like blackhole,
unreachable or prohibit) and multipath routes have no interface associated
with them, so ifname returns an empty string for such routes. **Setting it
would also change route to a direct one (remove gateway).**

Thanks, that did it; but unfortunately, further debugging revealed that bird seems to completely ignore such routes and they don't make it to the export filters, being discarded earlier.

Still the only option is to redeclare these as static.


Eugene.
