protocol ospf myospf {

        area 0 {

                interface "eth*" {

                        hello 10; retransmit 2; wait 10; dead 300; cost 10;

        };

}

Routes received from "eth1" will be _forwarded_ to "eth2" and bypassed all the filters. Is it possible to configure bird.conf so only some of the routes will be re-advertised? (aka apply filters to interface within the same OSPF area)

Creating multiple ospf instance and treat the routes as "external routes" (so filter will apply) is not a good idea for me because the environment is quite dynamic, may even have hundreds of dynamic virtual interface, and I hope I do not need to edit the config file all the time.

Thank you so much for your time.
