in networkd-route.c:route_new_static(), you currently set

        route->scope = RT_SCOPE_UNIVERSE;

Which sets up the following route:

localhost core # ip -4 route show
192.168.23.23 dev eth0 

…with this configuration:

    [Route]
    Destination=192.168.23.23/32

However, for my network setup, I need a route that is scoped to the link:

localhost core # ip -4 route delete 192.168.23.23 dev eth0
localhost core # ip -4 route add 192.168.23.23 dev eth0
localhost core # ip -4 route show
192.168.23.23 dev eth0  scope link 

…otherwise, I cannot set 192.168.23.23 as my default gateway.

Therefore, may I ask you to follow ip(8) in behavior, or make the route scope configurable please?

See http://michael.stapelberg.de/Artikel/kvm_best_practices_2012/ for the environment this is running in.

Thanks!
