网络优先级设置

DHCP方式的优先级

[DHCP]
RouteMetric = 200
静态方式的优先级

[Route]
Gateway = 192.168.1.1
Metric = 200

Metric的数字越小，优先级越高。

比如以太网eth0和4G设备的eth2设备，4G优先配置如下

[Match]
Name=eth2

[Network]
DHCP=yes

[DHCP]
RouteMetric = 100

以太网设备是静态IP，配置如下

[Match]
Name=eth0

[Network]
Address=192.168.1.100/24

[Route]
Gateway = 192.168.1.1
Metric = 200
