We're working on an Ubuntu 17.10 linux and we would have to use Netplan for network configuration. We have a /run/systemd/network/*.network file which fit what we need, but we want to "translate" it in a Netplan config file.
[Match] Name=ens18 [Network] Address=<guestIP>/32 Gateway=62.210.0.1 DHCP = none DNS=8.8.8.8 8.8.4.4 [Route] Destination=62.210.0.1/32 Scope = link We want to transpose this in the /etc/netplan/*.yaml file but we don't find how to do those two things:
- The scope = link doesn't seem to have a direct translation in the .yaml file. We're using it because we're working into a VM;
- The via line is required in the .yaml file when configuring route but 0.0.0.0 doesn't work.
With our configuration via the .network file, here is what route -n returns:
Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 62.210.0.1 0.0.0.0 UG 0 0 0 ens18 62.210.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ens18 So how to translate our two problematic lines in the Netplan config file?

Starting with netplan 0.34 (now in Ubuntu 18.04), you can add "scope: link" to your route in netplan config, with something like this:
network: version: 2 renderer: networkd ethernets: eth0: [...] gateway4: 62.210.0.1 routes: - to: 62.210.0.1/32 via: 62.210.0.1 scope: link
