Ubuntu 双网卡route

ip route flush table sz
ip route add default via 183.2.218.254 dev eth0 src 183.2.218.4 table sz
ip rule add from  183.2.218.4 table sz

ip route flush table hk
ip route add default via 45.124.25.254 dev eth1 src 45.124.25.221 table hk
ip rule add from 45.124.25.221 table hk

exit 0

注意exit 0要放后面,遇见执行报错，重启一下网卡

多路由情况下，如果遇见没有优先走你设置的路由，添加一条默认路由走指定的网关

route add default gw 45.124.25.254
