Operation Steps

One: Configure IP

A:ifconfig Ens33 172.100.0.100/16

Route add default GW 172.100.0.1

R1:ifconfig eth0 172.100.0.1/16

Ifconfig eth1 14.0.0.1/8

R2:ifconfig eth0 14.0.0.2/8

Ifconfig eth1 10.0.0.1/8

R3:ifconfig eth0 10.0.0.2/8

Ifconfig eth1192.168.0.1/24

B:ifconfig Ens33 192.168.0.100/24

Route add default GW 192.168.0.1

Two: Shut down the firewall of all machines

Iptables-f

Three: Open the R1 R2 machine routing function

Echo 1 >/PROC/SYS/NET/IPV4/IP_FORWD

Four: Add Route records

R1:route add-net 192.168.0.0/24 GW 14.0.0.2

Route add-net 10.0.0.0/8 GW 14.0.0.2

R2:route add-net 172.100.0.0/16 GW 14.0.0.2

Route add-net 192.168.0.1/24 GW 10.0.0.2

R3:route add-net 172.100.0.1/16 GW 10.0.0.1

Route add-net 14.0.0.0/8 GW 10.0.0.1

Note: Ifconfig added IP address may be lost, after the experiment if aping do not pass B please pingR1 R2 R3 each port, query the problem.
