【RIP配置实验】

• 实验拓扑

• 实验需求

1.R3环回3.3.3.0/24，不宣告此环回;
2.其他网段基于192.168.1.0/24进行划分;
3.R1与R2均存在两个环回;
4.整个网络运行ripv2;
5.全网可达，保证更新安全，减少路由条目

三、实验思路：

1.除了R3的环回地址固定3.3.3.0/24，其他网段基于192.168.1.0/24进行合理划分；

R1环回，R2环回，线1，线2? 共4个网段

192.168.1.0000 0000 24

R1? ???192.168.1.0000 0000 26

L0 192.168.1.0000 0000? 27

192.168.1.1? ?27?

L1?192.168.1.0010 0000? 27

192.168.1.33? ?27?

R2? ??192.168.1.0100 0000 26

L0??192.168.1.0100 0000? 27

192.168.1.65? ?27??

L1??192.168.1.0110 0000? 27

192.168.1.97? 27?

线1? ? 线2? ??192.168.1.1000 0000 26

1? ?192.168.1.1000 0000? 27

0? ?192.168.1.1000?0001? 28

1? 192.168.1.129? ? ?28

1? ?192.168.1.1001?0001? 28

2? ?192.168.1.145? ? 28

2? ??192.168.1.1010 0000? 27

0? ?192.168.1.1010?0001? 28

2? ?192.168.1.161? ? 28

1? ?192.168.1.1011?0001? 28

3? ?192.168.1.177? ? ?28

? ?192.168.1.1100 0000 26? （没用）

2.配 RIP协议，（路由协议不同不互通）选version2

3. R3? 上配默认路由

4.配置接口的认证模式

5.手工汇总并防环

6.测试

四、实验步骤

1.重命名和配IP

R1

[Huawei]sysname R1
[R1]int?? ?
[R1]interface g0/0/0
[R1-GigabitEthernet0/0/0]ip add?? ?
[R1-GigabitEthernet0/0/0]ip address 192.168.1.129 28

[R1-GigabitEthernet0/0/0]rip summary-address 192.168.1.128 ?
? IP_ADDR<X.X.X.X> ?IP address mask
[R1-GigabitEthernet0/0/0]rip summary-address 192.168.1.128 255.255.255.192

[R1-GigabitEthernet0/0/0]
[R1-GigabitEthernet0/0/0]
[R1-GigabitEthernet0/0/0]
[R1-GigabitEthernet0/0/0]quit

R2-GigabitEthernet0/0/0]rip summary-address 192.168.1.192 255.255.255.192
[R2-GigabitEthernet0/0/0]

[R2-GigabitEthernet0/0/1]quit

配防环静态路由

[R1]ip ro?? ?
[R1]ip route-s?? ?
[R1]ip route-static 192.168.1.128 26 n?? ?
[R1]ip route-static 192.168.1.128 26 NULL 0
