静态路由

实验需求:

完成三台路由器的配置（采用静态路由）；
完成两台PC的配置；完成配置后，两台PC要能够互相ping通。

R1的配置如下:

[R1] interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0] ip address 192.168.12.1 24
[R1] interface GigabitEthernet 0/0/1
[R1-GigabitEthernet0/0/1] ip address 192.168.1.254 24
#完成静态路由的配置，完成这条配置后，R1的路由表里就创建了一条静态路由，目的地是192.168.2.0/24网
络，下一跳为192.168.12.2：
[R1] ip route-static 192.168.2.0 24 192.168.12.2

R2的配置如下：

R3的配置如下：

在R2及R3上，分别查看路由表，也能够看到我们创建的静态路由。现在PC1与PC2就能够互相ping 通了。这里有一个遗留问题，PC1能够与PC2相互访问了，但是R1能够访问R3么？答案是R1与R3 无法互相互访

实现R1与R3互访

[R1]ip route-static 192.168.23.0 255.255.255.0 192.168.12.2
[R3]ip route

[R2] interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0] ip address 192.168.12.2 24
[R2] interface GigabitEthernet 0/0/1
[R2-GigabitEthernet0/0/1] ip address 192.168.23.2 24
[R2] ip route-static 192.168.1.0 24 192.168.12.1
[R2] ip route-static 192.168.2.0 24 192.168.23.3

[R3] interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0] ip address 192.168.23.3 24
[R3] interface GigabitEthernet 0/0/1
[R3-GigabitEthernet0/0/1] ip address 192.168.2.254 24
[R3] ip route-static 192.168.1.0 24 192.168.23.2
