it might actually make sense to provide a configuration option for the metric value here. And if not present just default to something that make sense. Seems like 1024 is pretty popular. Allowing different metrics for multi homing situation seems like a neat benefit. If by all means possible, add all routes provided by DHCP for eth0 with metric A and for eth1 use metric B. You never know what kind of datacenter network configuration you encounter. I have seen really crazy ones in my lifetime ;) Regards Marcel _______________________________________________ systemd-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/systemd-devel
