我有两个网络接口，eno1 和 eth0。我希望它们都使用 DHCP 获取 IP 地址。我希望 eno1 用作所有设备的默认路由。我唯一想使用 eth0 的情况是在 curl 命令中指定接口时。

我创建了两个配置文件：

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

我尝试过重新启动并调整指标，但它们似乎没有效果。
