Cisco基础实验回顾3--静态路由

拓扑图：

 

1. 配置IP地址

R1配置IP地址：

R1(config)#int loopback0

%LINK-5-CHANGED: Interface Loopback0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up
R1(config-if)#ip address 1.1.1.1 255.255.255.0
R1(config-if)#int s2/0

R1(config-if)#clock rate 128000
R1(config-if)#ip address 192.168.12.1 255.255.255.0
R1(config-if)#no shut

配置R2 IP：

R2(config)#int loopback0
R2(config-if)#ip address 2.2.2.2 255.255.255.0
R2(config-if)#int s2/0
R2(config-if)#clock rate 128000
R2(config-if)#ip address 192.168.12.2 255.255.255.0
R2(config-if)#no shut
 

R2(config-if)#int s3/0
R2(config-if)#clock rate 128000
R2(config-if)#ip address 192.168.23.2 255.255.255.0
R2(config-if)#no shut

 

配置R3 IP：

R3(config)#int loopback0
R3(config-if)#ip address 3.3.3.3 255.255.255.0
R3(config-if)#int s3/0
R3(config-if)#clock rate 128000
R3(config-if)#ip address 192.168.23.3 255.255.255.0
R3(config-if)#no shut
 

2. 配置静态路由

R1配置静态路由：

R1(config)#ip route 2.2.2.0 255.255.255.0 s2/0
R1(config)#ip route 3.3.3.0 255.255.255.0 s2/0

R2配置静态路由：

R2(config)#ip route 1.1.1.0 255.255.255.0 s2/0
R2(config)#ip route 3.3.3.0 255.255.255.0 s3/0

R3配置静态路由：

R3(config)#ip route 1.1.1.0 255.255.255.0 s2/0
R3(config)#ip route 2.2.2.0 255.255.255.0 s2/0

3. 实验测试

R1:

R1#sh 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

     1.0.0.0/24 is subnetted, 1 subnets
C       1.1.1.0 is directly connected, Loopback0
     2.0.0.0/24 is subnetted, 1 subnets
S       2.2.2.0 is directly connected, Serial2/0
     3.0.0.0/24 is subnetted, 1 subnets
S       3.3.3.0 [1/0] via 192.168.12.2
C    192.168.12.0/24 is directly connected, Serial2/0

 

R2:

R2#sh ip route
