 1.搭建拓扑

 

1.配置IP

[R1]int g 0/0/0
[R1-GigabitEthernet0/0/0]ip add 12.0.0.1 24 
[R1-GigabitEthernet0/0/0]int g 0/0/1
[R1-GigabitEthernet0/0/1]ip add 14.0.0.1 24
[R1-GigabitEthernet0/0/1]int l 0
[R1-LoopBack0]ip add 1.1.1.1 24
[R1-LoopBack0]int l 1          
[R1-LoopBack1]ip add 172.16.1.1 24
[R1-LoopBack1]int l 2        
[R1-LoopBack2]ip add 172.16.2.1 24
[R1-LoopBack2]int l 3        
[R1-LoopBack3]ip add 172.16.3.1 24
[R1-LoopBack3]int l 4        
[R1-LoopBack4]ip add 172.16.4.1 24
 

[R2]int g 0/0/0
[R2-GigabitEthernet0/0/0]ip add 12.0.0.2 24
[R2-GigabitEthernet0/0/0]int g 0/0/1       
[R2-GigabitEthernet0/0/1]ip add 23.0.0.2 24
[R2-GigabitEthernet0/0/1]int l 0
[R2-LoopBack0]ip add 2.2.2.2 24

[R3]int g 0/0/0
[R3-GigabitEthernet0/0/0]ip add 34.0.0.3 24
[R3-GigabitEthernet0/0/0]int g 0/0/1       
[R3-GigabitEthernet0/0/1]ip add 23.0.0.3 24 
[R3-GigabitEthernet0/0/1]int l 0
[R3-LoopBack0]ip add 3.3.3.3 24
 
[R4]int g 0/0/0
[R4-GigabitEthernet0/0/0]ip add 34.0.0.4 24. 
[R4-GigabitEthernet0/0/0]int g 0/0/1       
[R4-GigabitEthernet0/0/1]ip add 14.0.0.4 24
[R4-GigabitEthernet0/0/1]int l 0
[R4-LoopBack0]ip add 4.4.4.4 24

2.分别启动rip以及ospf协议

[R1]rip 1
[R1-rip-1]version 2
[R1-rip-1]undo summary
[R1-rip-1]network 12.0.0.0
[R1-rip-1]network 1.0.0.0
[R1-rip-1]network 14.0.0.0
[R1-rip-1]network 172.16.0.0
 
[R2]rip 1
[R2-rip-1]version 2
[R2-rip-1]undo summary
[R2-rip-1]network 12.0.0.0
[R2-rip-1]network 2.0.0.0
[R2]ospf 1 router-id 2.2.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 23.0.0.2 0.0.0.0
 
[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 23.0.0.3 0.0.0.0
[R3-ospf-1-area-0.0.0.0]network 34.0.0.3 0.0.0.0
[R3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0
 
[R4]ospf 1 router-id 4.4.4.4
[R4-ospf-1]area 0
[R4-ospf-1-area-0.0.0.0]network 34.0.0.4 0.0.0.0
[R4-ospf-1-area-0.0.0.0]network 4.4.4.4 0.0.0.0
[R4]rip 1
[R4-rip-1]version 2
[R4-rip-1]undo summary
[R4-rip-1]network 14.0.0.0

3.重发布

[R2]ospf 1
[R2-ospf-1]import-route rip
[R2-ospf-1]rip 1
[R2-rip-1]import-route ospf
 
[R4]ospf 1
[R4-ospf-1]import-route rip
[R4-ospf-1]rip 1
[R4-rip-1]import-route ospf

4.修改R4环回接口的网络类型为Broad cast

[R4-LoopBack0]ospf network-type broadcast

5..更改最佳选路

[R1]ip ip-prefix aa permit 24.1.1.0 24

[R1-GigabitEthernet0/0/1]rip metricin ip-prefix aa 2

[R1]ip ip-prefix bb permit 36.1.1.0 24
[R1-GigabitEthernet0/0/0]rip metricin ip-prefix bb 2

[R1]ip ip-prefix cc permit 192.168.4.0 24
[R1-GigabitEthernet0/0/0]rip metricin ip-prefix cc 2
6.R1除本身环回外，外加几条环回

172.16.1.0/24 deny

172.16.2.0/24 type 1

172.16.3.0/24 cost 6

172.16.4.0/24 type 1 cost 9
更改如上参数

R2]ip ip-prefix 1 permit 172.16.1.0 24 
[R2]ip ip-prefix 2 permit 172.16.2.0 24 
[R2]ip ip-prefix 3 permit 172.16.3.0 24
[R2]ip ip-prefix 4 permit 172.16.4.0 24

[R2]route-policy huawei deny node 10
[R2-route-policy]if-match ip-prefix 1

[R2]route-policy huawei permit node 20
[R2-route-policy]if-match ip-prefix 2
[R2-route-policy]apply cost-type type-1

[R2]route-policy huawei permit node 30
[R2-route-policy]if-match ip-prefix 3
[R2-route-policy]apply cost-type type-1
[R2-route-policy]apply cost 6

[R2]route-policy huawei permit node 40
[R2-route-policy]if-match ip-prefix 4
[R2-route-policy]apply cost-type type-1       
[R2-route-policy]apply cost 9

[R2-ospf-1]import-route rip 1 route-policy huawei

[R2]route-policy huawei permit  node 50  

[R4]ip ip-prefix haha permit 172.16.1.0 24
[R4]route-policy xixi deny node 10
[R4-route-policy]if-match ip-prefix xixi
[R4-ospf-1]import-route rip 1 route-policy xu
实验结果
