静态路由

拓扑图

• 掌握静态路由的配置方法
• 掌握实现本地网络与外部网路的访问

配置IP地址

[R2]interface Serial 0/0/0
[R2-Serial0/0/0]ip address 10.0.12.2 24 
[R2]interface Serial 0/0/1
[R2-Serial0/0/1]ip address 10.0.23.2 24 

[R3]interface Serial 0/0/0
[R3-Serial0/0/0]ip address 10.0.12.1 24 
[R3]interface Serial 0/0/2
[R3-Serial0/0/2]ip address 10.0.13.1 24 

[R4]interface Serial 0/0/1
[R4-Serial0/0/1]ip address 10.0.23.3 24 
[R4]interface Serial 0/0/2
[R4-Serial0/0/2]ip address 10.0.13.3 24

 测试连通性

[R2]ping  -c 1 10.0.12.1 
  PING 10.0.12.1: 56  data bytes, press CTRL_C to break
    Reply from 10.0.12.1: bytes=56 Sequence=1 ttl=255 time=30 ms

  --- 10.0.12.1 ping statistics ---
    1 packet(s) transmitted
    1 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 30/30/30 ms

[R2]ping -c 1 10.0.13.1
  PING 10.0.13.1: 56  data bytes, press CTRL_C to break
    Request time out

  --- 10.0.13.1 ping statistics ---
    1 packet(s) transmitted
    0 packet(s) received
    100.00% packet loss

  PING 10.0.13.1: 56  data bytes, press CTRL_C to break
    Reply from 10.0.13.1: bytes=56 Sequence=1 ttl=254 time=30 ms

缺省路由

[R2]ip route-static 0.0.0.0 0 10.0.12.1
