静态路由的优缺点

优点：
1、静态路由比动态路由更可控
2、静态路由比动态路由更容易部署

缺点：
1、扩展性差
2、不适应拓扑变化

实践1

[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ip address 192.168.123.1 24
[R1-GigabitEthernet0/0/0]undo shutdown 
Info: Interface GigabitEthernet0/0/0 is not shutdown.
[R1-GigabitEthernet0/0/0]quit 
[R1]interface  GigabitEthernet 0/0/1    
[R1-GigabitEthernet0/0/1]ip address 10.0.14.1 29
[R1-GigabitEthernet0/0/1]undo shutdown 
Info: Interface GigabitEthernet0/0/1 is not shutdown.

[R2]interface GigabitEthernet 0/0/0 
[R2-GigabitEthernet0/0/0]ip address 192.168.123.2 24
[R2-GigabitEthernet0/0/0]undo shutdown 
Info: Interface GigabitEthernet0/0/0 is not shutdown.
[R2-GigabitEthernet0/0/0]quit

[R3]interface GigabitEthernet 0/0/0 
[R3-GigabitEthernet0/0/0]ip address 192.168.123.3 24
[R3-GigabitEthernet0/0/0]undo shutdown 
Info: Interface GigabitEthernet0/0/0 is not shutdown.

[R4]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]ip add 
[R4-GigabitEthernet0/0/0]ip address 10.0.14.4 29
[R4-GigabitEthernet0/0/0]undo shu   
[R4-GigabitEthernet0/0/0]undo shutdown 
Info: Interface GigabitEthernet0/0/0 is not shutdown.

[R2]ip route-static 10.0.14.0 29 192.168.123.1 #配置静态路由
[R3]ip route-static 10.0.14.0 29 GigabitEthernet 0/0/0 192.168.123.1 #配置静态路由

测试

小结

1、配置了静态路由后不要忘记配置回程路由
2、配置静态路由下一跳必须配置IP地址，在点对点串行链路中可以使用出接口作为下一跳
