interface Serial1/0
ipaddress 192.168.1.2 255.255.255.0
interface Serial1/1
ipaddress 192.168.2.1 255.255.255.0
R3
interface Loopback0
ip address 192.168.3.1255.255.255.0
interface Serial1/1
ip address 192.168.2.2255.255.255.0
路由配置
R1
ip route 192.168.2.0 255.255.255.0 192.168.1.2 \\到R2去的路由
ip route 192.168.3.0 255.255.255.0 192.168.1.2 \\到R3去的路由
R2
ip route 0.0.0.0 0.0.0.0 192.168.1.1 \\到R1的返回路由
ip route 192.168.3.0 255.255.255.0 192.168.2.2 \\到R3的路由
R3
ip route 0.0.0.0 0.0.0.0 192.168.2.1 \\只用一条返回路由就可以

测试：
R1#ping 192.168.3.1 source 192.168.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to192.168.3.1, timeout is 2 seconds:
Packet sent with a source address of192.168.0.1
!!!!!
Success rate is 100 percent (5/5),round-trip min/avg/max = 60/68/92 ms
