静态综合路由实验
实验拓扑
实验要求
1.除R5的环回地址外,整个其他所有网段基于192.168.1.0/24进行合理的IP地址划分
2.R1-R4每个路由器存在两个环回接口,用于模拟pc网段;地址也在192.168.1.0/24这个网络范围内
3.R1-R4上不能直接编写到达5.5.5.0/24的静态路由,但依然可以访问
4.全网可达,尽量减少每台路由器,路由表条目数量,避免环路出现
5.R4与R5间,正常1000m链路通信,故障时自动改为100m
实验步骤
第一步:划分网段
由题意知,需要6个骨干网线IP地址,8个环回接口,且需尽量减少每台路由器,路由表条目数量,避免环路出现,于是如下划分:
第二步:改名,配置IP地址、环回接口
先对五个路由器进行改名操作,然后开始配置IP地址(具体方法不一一阐述,不会的可以参考eNSP基础命令),环回接口。如下:
r1:
[R1]int g 0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 30
[R1-GigabitEthernet0/0/0]int g 0/0/1
[R1-GigabitEthernet0/0/1]ip add 192.168.1.5 30
[R1-GigabitEthernet0/0/1]int l0
[R1-LoopBack0]ip add 192.168.1.33 28
[R1-LoopBack0]int l1
[R1-LoopBack1]ip add 192.168.1.49 28
r2:
[R2]int g 0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.1.2 30
[R2-GigabitEthernet0/0/0]int g 0/0/1
[R2-GigabitEthernet0/0/1]ip add 192.168.1.9 30
[R2-GigabitEthernet0/0/1]int l0
[R2-LoopBack0]ip add 192.168.1.65 28
[R2-LoopBack0]int l1
[R2-LoopBack1]ip add 192.168.1.81 28
r3:
[R3]int g 0/0/0
[R3-GigabitEthernet0/0/0]ip add 192.168.1.6 30
[R3-GigabitEthernet0/0/0]int g 0/0/1
[R3-GigabitEthernet0/0/1]ip add 192.168.1.13 30
[R3-GigabitEthernet0/0/1]int l0
[R3-LoopBack0]ip add 192.168.1.97 28
[R3-LoopBack0]int l1
[R3-LoopBack1]ip add 192.168.1.113 28
r4:
[R4]int g 0/0/0
[R4-GigabitEthernet0/0/0]ip add 192.168.1.14 30
[R4-GigabitEthernet0/0/0]int g 0/0/1
[R4-GigabitEthernet0/0/1]ip add 192.168.1.10 30
[R4-LoopBack1]int g 0/0/2
[R4-GigabitEthernet0/0/2]ip add 192.168.1.17 30
[R4-GigabitEthernet0/0/2]int g 4/0/0
[R4-GigabitEthernet4/0/0]ip add 192.168.1.21 30
[R4-GigabitEthernet0/0/1]int l0
[R4-LoopBack0]ip add 192.168.1.129 28
[R4-LoopBack0]int l1
[R4-LoopBack1]ip add 192.168.1.145 28
r5:
[R5]int g 0/0/0
[R5-GigabitEthernet0/0/0]ip add 192.168.1.18 30
[R5-GigabitEthernet0/0/0]int g 0/0/1
[R5-GigabitEthernet0/0/1]ip add 192.168.1.22 30
[R5-GigabitEthernet0/0/1]int l0
[R5-LoopBack0]ip add 5.5.5.5 24
第三步:配置静态路由与空接口、配置浮动静态路由
配置静态路由,因为需要将R1,R2,R3,R4上每个网段进行汇总,且需要避免路由环路出现,所以还需要配置空接口。向r5中设置缺省路由,为了不直接编写5.5.5.0/24也能到5.5.5.0/24网段;配置浮动静态路由,调整优先级设置
全部配置完成以后,可实现全网通。

第四步:检测是否全网可通
测试得全网可通,断开r4的0/0/2接口,再次ping,依旧能通(不一一演示),如图:
[R4]int g 0/0/2
[R4-GigabitEthernet0/0/2]shutdown
至此,实验成功结束!!
