Tenho duas interfaces de rede, eno1 e eth0. Gostaria que ambas usassem DHCP para obter um endereço IP. Gostaria que eno1 fosse usado como rota padrão para tudo. A única vez que quero usar eth0 é ao especificar interface em um comando curl.

Criei dois arquivos de configuração:

root:/etc/systemd/network$ ls -la
total 16
drwxr-xr-x 2 root root 4096 Oct 20 10:50 .
drwxr-xr-x 6 root root 4096 Oct 20 10:51 ..
-rw-r--r-- 1 root root   59 Oct 20 09:54 10-eno1.network
-rw-r--r-- 1 root root   59 Oct 20 10:41 20-eth0.network

root:/etc/systemd/network$ cat 10-eno1.network
[Match]
Name=eno1

[Network]
DHCP=yes

[Route]
Metric=100

root:/etc/systemd/network$ cat 20-eth0.network
[Match]
Name=eth0

[Network]
DHCP=yes

[Route]
Metric=4000

Tentei reiniciar e mexer nas métricas, mas elas não surtiram efeito.
