第五步：在ROUTER-A 上PING 路由器C
Router-A#ping 192.168.2.2
PING 192.168.2.2 (192.168.2.2): 56 data bytes
.....
--- 192.168.2.2 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss ！不通
第六步：在路由器A 上配置静态路由
Router-A#config Router-A_config#ip route 192.168.2.0 255.255.255.0 192.168.1.2 ！配置目标网段和下一跳
Router-A_config#ip route 192.168.3.0 255.255.255.0 192.168.1.2
第七步：查看路由表
Router-A#show ip route
Codes: C - connected, S - static, R - RIP, B - BGP, BC - BGP connected
D - DEIGRP, DEX - external DEIGRP, O - OSPF, OIA - OSPF inter area
ON1 - OSPF NSSA external type 1, ON2 - OSPF NSSA external type 2
OE1 - OSPF external type 1, OE2 - OSPF external type 2
DHCP - DHCP type
VRF ID: 0
C 192.168.0.0/24 is directly connected, FastEthernet0/0
C 192.168.1.0/24 is directly connected, Serial1/1
S 192.168.2.0/24 [1,0] via 192.168.1.2 ！注意静态路由的管理距离是1
S 192.168.3.0/24 [1,0] via 192.168.1.2
第八步：配置路由器B 的静态路由并查看路由表
Router-B#config
Router-B_config#ip route 192.168.0.0 255.255.255.0 192.168.1.1
Router-B_config#ip route 192.168.3.0 255.255.255.0 192.168.2.2
Router-B_config#^Z
Router-B#show ip route

S 192.168.3.0/24 [1,0] via 192.168.2.2
第九步：配置路由器C 的静态路由并查看路由表
Router-C#config
Router-C_config#ip route 192.168.0.0 255.255.0.0 192.168.2.1 ！采用超网的方法
Router-C_config#^Z
Router-C#show ip route
Codes: C - connected, S - static, R - RIP, B - BGP
D - DEIGRP, DEX - external DEIGRP, O - OSPF, OIA - OSPF inter area ON1 - OSPF NSSA external type 1, ON2 - OSPF NSSA external type 2
OE1 - OSPF external type 1, OE2 - OSPF external type 2
