IP tunnels use IP addresses assigned to other IP interfaces as their "link-layer" source addresses, so yes, they depend on other IP interfaces on the system having been setup. I don't see how this would directly lead to the conclusion that the IP tunneling service needs to depend on milestone/network. Why wouldn't an administrator view milestone/network as including the configuration of IP tunnel interfaces? The IP tunneling service could very well depend on an individual service that is responsible for "non-IP-tunnel" IP interfaces rather than the broader milestone/network. -Seb
