【网络】重发布实验

题目

一、实验拓扑

二、实验需求

1.双点双向重发布、所有选路最佳

2.且存在备份路径

三、实验思路

1.配置IP

2.配置RIP,OSPF

3.双点双向重发布

4.所有选路最佳,且存在备份路径

四、实验步骤

1.配置IP

[r1]int lo 0
[r1-LoopBack0]ip address 1.1.1.1 24
[r1-LoopBack0]int g0/0/1
[r1-GigabitEthernet0/0/1]ip address 12.1.1.1 24
[r1-GigabitEthernet0/0/1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip address 14.1.1.1 24

[r2]int lo 0
[r2-LoopBack0]ip address 2.2.2.2 24
[r2-LoopBack0]int g 0/0/0
[r2-GigabitEthernet0/0/0]ip address 12.1.1.2 24
[r2-GigabitEthernet0/0/0]int g 0/0/1
[r2-GigabitEthernet0/0/1]ip address 23.1.1.1 24

[r3]int lo 0
[r3-LoopBack0]ip address 3.3.3.3 24
[r3-LoopBack0]int g 0/0/0
[r3-GigabitEthernet0/0/0]ip address 23.1.1.2 24
[r3-GigabitEthernet0/0/0]int g 0/0/1
[r3-GigabitEthernet0/0/1]ip address 34.1.1.2 24

[r4]int lo 0
[r4-LoopBack0]ip address 4.4.4.4 24
[r4-LoopBack0]int g 0/0/1
[r4-GigabitEthernet0/0/1]ip address 34.1.1.1 24
[r4-GigabitEthernet0/0/1]int g 0/0/0
[r4-GigabitEthernet0/0/0]ip address 14.1.1.2 24

2.配置RIP,OSPF

[r1]rip 1
[r1-rip-1]vers 2
[r1-rip-1]network 1.0.0.0
[r1-rip-1]network 12.0.0.0
[r1-rip-1]network 14.0.0.0

[r2]rip 1	
[r2-rip-1]version 2	
[r2-rip-1]network 2.0.0.0	
[r2-rip-1]network 12.0.0.0
[r2-rip-1]q
[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]network 23.1.1.1 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 3.3.3.3 0.0.0.0
[r3-ospf-1-area-0.0.0.0]network 23.1.1.2 0.0.0.0
[r3-ospf-1-area-0.0.0.0]network 34.1.1.2 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 4.4.4.4 0.0.0.0
[r4-ospf-1-area-0.0.0.0]network 34.1.1.1 0.0.0.0
[r4-ospf-1-area-0.0.0.0]q
[r4-ospf-1]q
[r4]rip 1
[r4-rip-1]version 2
[r4-rip-1]network 14.0.0.0

3.双点双向重发布

[r2]ospf 1
[r2-ospf-1]import-route rip 1
[r2-ospf-1]q
[r2]rip 
[r2-rip-1]import-route ospf 1

[r4]ospf 1
[r4-ospf-1]import-route rip 1
[r4-ospf-1]q
[r4]rip 1
[r4-rip-1]import-route ospf 1

//更改环回接口工作方式，防止路由回馈
[r4]int lo 0	
[r4-LoopBack0]ospf network-type b	
[r4-LoopBack0]ospf network-type broadcast 

//也可以
[r4-LoopBack0]ip address 4.4.4.4 24

4.路由策略，所有选路最佳,且存在备份路径

//在R3的出接口上对2.2.2.0/24加度量
[r4]ip ip-prefix ww permit 2.2.2.0 24
[r4]int g 0/0/0
[r4-GigabitEthernet0/0/0]rip metricout ip-prefix ww 2
	
[r2]ip ip-prefix a permit 14.1.1.0 24
