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:
