三个路由器的静态路由

    设置RouterA的IP:
f0/0: 10.65.1.2  --->PCA:10.65.1.1
f0/1: 10.66.1.2  --->PCB:10.66.1.1
s0/0: 10.67.1.2
s0/1: 10.68.1.2  --->接RouterC s0/0

    设置RouterC的IP:
s0/0: 10.68.1.1  <---
s0/1: 10.78.1.2  --->接RouterB s0/0

    设置RouterB的IP:
s0/0: 10.78.1.1  <---
s0/1: 10.67.1.1
f0/0: 10.69.1.2  --->PCC:10.69.1.1
f0/1: 10.70.1.2  --->PCD:10.70.1.1

    设置从PCA到PCC的静态路由
ROA(config)#ip routing
ROA(config)#ip route 10.69.0.0 255.255.0.0 10.68.1.1
ROA#show ip route
ROB(config)#ip route 10.69.0.0 255.255.0.0 10.78.1.1
ROB#show ip route
[root@PCA root]#ping 10.69.1.1 (通)
[root@PCA root]#ping 10.78.1.1 (不通)
[root@PCA root]#ping 10.70.1.1 (不通)

    我们再做一个使用默认路由的小实验，先去掉原有的静态路由。
ROA(config)#no ip route 10.69.0.0 255.255.0.0 10.68.1.1
ROA#sh ip ro

ROB(config)#no ip route 10.69.0.0 255.255.0.0 10.78.1.1
ROB#sh ip ro

[root@PCA root]#ping 10.69.1.1 (不通)

ROA(config)#ip route 0.0.0.0. 0.0.0.0 10.68.1.1
ROA#sh ip ro

ROB(config)#ip route 0.0.0.0. 0.0.0.0 10.69.1.1
