我希望 systemd-networkd 忽略一个接口上由 DHCP 推送的默认路由。
我的工作设置有 3 个网络接口。每个接口都有一个 .network 文件：
eth0：互联网
[Match]
Name=eth0
[Network]
DHCP=yes
DNS=127.0.0.1
eth1：本地测试网络
[Match]
Name=eth1
[Network]
Address=192.168.78.1/24
IPForward=ipv4
IPMasquerade=yes
DHCPServer=yes
[DHCPServer]
PoolOffset=10
PoolSize=100
EmitDNS=yes
DNS=192.168.78.1
eth2：VPN 路由器连接到主站点。
[Match]
Name=eth2
[Network]
DHCP=ipv4
[Route]
Gateway=10.3.10.1
Destination=10.100.102.0/24
Metric=0
[Route]
Gateway=10.3.10.1
Destination=10.3.13.0/24
Metric=0
[Route]
Gateway=10.3.10.1
Destination=10.3.14.0/24
Metric=0
[DHCP]
UseDNS=false
SendHostname=true
UseRoutes=false
RouteMetric=2000
vnet0：不与虚拟机实际接口连接的桥接接口
[Match]
Name=vnet0
[Network]
Address=192.168.77.1/24
IPForward=ipv4
IPMasquerade=yes
DHCPServer=yes
[DHCPServer]
PoolOffset=10
PoolSize=100
EmitDNS=yes
DNS=192.168.77.1
如您所见，UseRoutes=false已设置完毕，并且在 eth2 网络上仍然有默认路由：
default via 192.168.178.1 dev eth0 proto dhcp src 192.168.178.52 metric 1024
default via 10.3.10.1 dev eth2 proto dhcp src 10.3.10.196 metric 2000
10.3.10.0/24 dev eth2 proto kernel scope link src 10.3.10.196
10.3.10.1 dev eth2 proto dhcp scope link src 10.3.10.196 metric 2000
192.168.77.0/24 dev vnet0 proto kernel scope link src 192.168.77.1 linkdown
192.168.78.0/24 dev eth1 proto kernel scope link src 192.168.78.1
192.168.178.0/24 dev eth0 proto kernel scope link src 192.168.178.52
192.168.178.1 dev eth0 proto dhcp scope link src 192.168.178.52 metric 1024
我也尝试过，UseRoutes=no但没有任何区别。有人知道我做错了什么吗？
