该博客详细介绍了配置静态路由的三个步骤：基础静态路由、浮动静态路由和缺省路由。通过配置路由器接口IP、添加静态路由条目以及设置浮动静态路由和缺省路由，实现了网络间的连通性，并通过ping测试验证了配置的有效性。

 步骤

实现此案例需要按照如下步骤进行。
步骤一：配置静态路由

1）R1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

2)R2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

3）R1上添加静态路由

R1(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2

4）R1上查看路由表

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                     //S表示静态路由
5）R2上添加静态路由
R2(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1
6）R2上查看路由条目
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）配置PC1的IP地址为192.168.1.1，网关为192.168.1.254
8）配置PC2的IP地址为192.168.3.1，网关为192.168.3.254
9）测试网络连通性,PC1 ping 192.168.3.1
PC>ping 192.168.3.1
