the FAQ refers to 4.4 (i.e. the last released version), but I'm pretty sure this particular thing (link down resulting in blackhole) is not a problem in -current. you may still have a need for some other way to kill the route if the link stays up but the nexthop is down, though. > So use ifstated to check the link of the interface and populate the > routing table accordingly. as an alternative to ifstated, you could take default routes from OSPF if your environment allows. (ospfd is ECMP capable).
