routing protocol), in most cases it is not needed to have these device
routes in BIRD routing table and to use the direct protocol.
<p>There is one notable case when you definitely want to use the
direct protocol -- running BIRD on BSD systems. Having high priority
device routes for directly connected networks from the direct protocol
protects kernel device routes from being overwritten or removed by IGP
routes during some transient network conditions, because a lower
priority IGP route for the same network is not exported to the kernel
routing table. This is an issue on BSD systems only, as on Linux
systems BIRD cannot change non-BIRD route in the kernel routing table.
<p>The only configurable thing about direct is what interfaces it watches:
