串行线路和静态路由配置

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname R1
R1(config)#

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname R2
R2(config)#

3.查看路由器的串行控制信息

R1#show controllers serial 0/0/0

4.配置R1和R2串行接口

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#interface serial 0/0/0       #指定串行接口
R1(config-if)#desc WAN Link to R2       #添加接口描述
R1(config-if)#ip add 192.168.1.1 255.255.255.0      #配置ip地址
R1(config-if)#clock rate 500000     #DCE端配置时钟频率
R1(config-if)#no shutdown

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R2(config)#interface serial 0/0/0
R2(config-if)#desc WAN Link to R1
R2(config-if)#ip add 192.168.1.2 255.255.255.0
R2(config-if)#no shutdown

5.测试连通性（R1 PING R2 & R2 PING R1）

6.配置路由器以太网口

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#interface f0/0
R1(config-if)#desc LAN Link to R1
R1(config-if)#ip add 10.0.0.1 255.0.0.0
R1(config-if)#no shutdown

R2#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R2(config)#inter
R2(config)#interface f0/0
R2(config-if)#desc LAN Link to R1
R2(config-if)#ip add 10.0.0.1 255.0.0.0
R2(config-if)#no shutdown

7.配置主机信息

8.测试路由器连通性

ping 192.168.1.2
ping 10.255.255.254

ping 192.168.1.1
ping 172.16.255.254

9.查看路由信息

R1#show ip route
此时只有直连路由，缺少到网络172.16.0.0/16的路由

R2#show ip route
缺少到网络10.0.0.0/8的路由

10.在R1配置静态路由

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#ip route 172.16.0.0 255.255.0.0 192.168.1.2
R1(config)#

11.查看R1路由信息

show ip route

12.在R2配置静态路由

R2#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R2(config)#ip route 10.0.0.0 255.0.0.0 192.168.1.1
R2(config)#

13.查看R2路由信息

show ip route

14.测试连通性

ping 10.255.255.254

ping 172.16.255.254
