作用:(Ubuntu20.04系统启动后直接加载固定路由)让本机一启动就把 192.168.0.2 / .4 / .102 / .104 / .106 这 5 个地址“当成跟自己同一链路(link)上的邻居”,无需网关即可直达,ARP 解析后直接发包。
目录位置: /etc/systemd/network/10-enp1s0.network
配置完成,重启(sudo systemctl enable systemd-networkd)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
| [Match] Name=enp1s0
[Network] DHCP=yes
# 下面 5 行就是固定路由 [Route] Destination=192.168.0.2/32 Scope=link
[Route] Destination=192.168.0.4/32 Scope=link
[Route] Destination=192.168.0.102/32 Scope=link
[Route] Destination=192.168.0.104/32 Scope=link
[Route] Destination=192.168.0.106/32 Scope=link
