静态路由实验(2)

发布于:2025-07-12 ⋅ 阅读:(36) ⋅ 点赞:(0)

一、实验拓扑图

广播域有15个

二 、实验要求

1.除了R5的环回地址固定5.5.5.0/24,其他网段基于192.168.1.0/24进行合理划分;
2.R1-R4每个路由器存在两个环回接口,模拟PC,地址也在192.168.1.0/24网络内;
3.R1-R4不能直接编写到达5.5.5.0/24的静态路由,但依然可以访问;----利用缺省路由
4.全网可达,尽量减少每台路由器路由条目数量(利用环回口的路由汇总),避免环路(利用空接口防环);
5.R4与R5间,正常1000M链路通信,故障时自动改为100M。----更改静态路由的优先级

三、实验步骤

4、配缺省路由(能够访问5.5.5.0/24的静态路由)

R1

[R1]ip route-static 0.0.0.0 0 192.168.1.2
[R1]ip route-static 0.0.0.0 0 192.168.1.6

R2

[R2]ip route-static 0.0.0.0 0 192.168.1.10

R3

[R3]ip route-static 0.0.0.0 0 192.168.1.14

R4

[R4]ip route-static 0.0.0.0 0 192.168.1.18
[R4]ip route-static 0.0.0.0 0 192.168.1.22

5、在路由上配防环(只有环回口,才能利用空接口防止环路)

R1

[R1]ip route-static 192.168.1.32 27 NULL 0

R2

[R2]ip route-static 192.168.1.64 27 NULL 0

R3

[R3]ip route-static 192.168.1.96 27 NULL 0

R4

[R4]ip route-static 192.168.1.128 27 NULL 0

R5不用配,因为没有路由汇总

6、修改优先级

R4

R5

[R5]ip route-static 192.168.1.0 255.255.255.252 192.168.1.21 pre 61

[R5]
[R5]ip route-static 192.168.1.96 255.255.255.224 192.168.1.21 pre 61

[R5]display ip routing-table protocol static 

四、测试

1、测试全网通;

同理,在其他路由器可以进行ping测试,查看是否全网通。

2、测试R4与R5间,正常1000M链路通信,故障时自动改为100M。

(1)断开1000M线路

(2)在R1进行测试
