静态路由配置
配置静态路由实现两个不同网络之间的全网互通
1）搭建网络拓扑
2）配置PC1的IP地址为192.168.1.1，网关为192.168.1.254
配置PC2的IP地址为192.168.2.1，网关为192.168.2.254
3）router1上配置接口IP
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address 192.168.1.254 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface fastEthernet 0/1
R1(config-if)#ip address 192.168.2.1 255.255.255.0
R1(config-if)#no shutdown
4）router2上配置接口IP
R2(config)#interface fastEthernet 0/1
R2(config-if)#ip address 192.168.2.2 255.255.255.0
R2(config-if)#no shutdown
R2config-if)#exit
R2(config)#interface fastEthernet 0/0
R2(config-if)#ip address 192.168.3.254 255.255.255.0
R2(config-if)#no shutdown
5）在router1上添加静态路由并产看路由表
R1(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2
R1#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.1.0/24 is directly connected, FastEthernet0/0
C 192.168.2.0/24 is directly connected, FastEthernet0/1
S 192.168.3.0/24 [1/0] via 192.168.2.2
6）在router2上添加静态路由并查看路由表
R2(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1
R2#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
S 192.168.1.0/24 [1/0] via 192.168.2.1 //S表示静态路由
C 192.168.2.0/24 is directly connected, FastEthernet0/1
C 192.168.3.0/24 is directly connected, FastEthernet0/0
7）测试网络连通性，在pc1上ping192.168.3.1

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss
2. 配置静态路由是吸纳三个不同网络的连通性
1）搭建网络拓扑结构
2）配置pc1的IP地址192.168.1.1，网关为192.168.1.254
配置PC2的IP地址192.168.4.1，网关为192.168.4.254
3）在router1上配置接口IP
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address 192.168.1.254 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface fastEthernet 0/1
R1(config-if)#ip address 192.168.2.1 255.255.255.0
