兩臺主機指向各自路由
route1
cd /etc/sysconfig/network-scripts/ vim ifcfg-eth0 cp ifcfg-eth0 ifcfg-eth1 vim ifcfg-eth1 nmcli con reload nmcli con up eth0 ip a
#開啟路由轉發 echo 1 > /proc/sys/net/ipv4/ip_forward cat /proc/sys/net/ipv4/ip_forward route -n ip a route add -net 172.20.0.0/16 gw 172.18.0.201 dev eth1 route add-net 172.22.0.0/16 gw 172.18.0.201 dev eth1 route -n route del -net 172.22.0.0/16 gw 172.18.0.201 dev eth1 route del -net 172.20.0.0/16 gw 172.18.0.201 dev eth1 route -n
#因為是邊路，所以換成預設路由也可以 route add default gw 172.18.0.201 dev eth1
route2
cd /etc/sysconfig/network-scripts/ vim ifcfg-eth0 cp ifcfg-eth0 ifcfg-eth1 vim ifcfg-eth1 nmcli con reload nmcli con up eth0 ip a ping 172.18.0.200 echo 1 > /proc/sys/net/ipv4/ip_forward cat /proc/sys/net/ipv4/ip_forward route add -net 172.16.0.0/16 gw 172.18.0.200 dev eth0 route add -net 172.22.0.0/16 gw 172.20.0.201 dev eth1 route -n
route3
cd /etc/sysconfig/network-scripts/ vim ifcfg-eth0 cp ifcfg-eth0 ifcfg-eth1 vim ifcfg-eth1 nmcli con reload nmcli con up eth0 ping 172.20.0.200 echo 1 > /proc/sys/net/ipv4/ip_forward cat /proc/sys/net/ipv4/ip_forward route add default gw 172.20.0.200 dev eth0 ping 172.16.0.200
