重发布实验

实验要求

1.两个协议间进行多点双向重发布

2.r7的环回没有宣告在ospf协议中，而是后期发布进入的

3.解决环路，所有路径选择最优，且存在备份

实验拓扑图

实验流程

配置IP及环回

R1

R2

R3

R4

R5

R6

R7

配置rip及ospf

[r1]rip 1
[r1-rip-1]ver 2 
[r1-rip-1]network 1.0.0.0  
[r1-rip-1]network 12.0.0.0    
[r1-rip-1]network 13.0.0.0

R2：

[r2]rip 1 

[r2-rip-1]ver 2

[r2-rip-1]network 12.0.0.0

[r2-rip-1]network 2.0.0.0

R4:

[r4-rip-1]network 41.0.0.0

[r4]ospf 1 router-id 4.4.4.4

[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 34.1.1.2 0.0.0.0

 

 

 

 

 

重发布

R2：

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

[r2-ospf-1]import-route rip

R4：

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

[r4-ospf-1]import-route rip

防环 修改优先级，在R3，R2上解除环路

r3:
[r3]ip ip-prefix b permit 7.7.7.0 24
[r3]route-policy bb permit node 10  
[r3-route-policy]if-match ip-prefix b   
[r3-route-policy]apply  preference 151

[r3]ip ip-prefix y permit 24.1.1.0 24
[r3]int g0/0/0  
[r3-GigabitEthernet0/0/0]rip metricout ip-prefix y 2

[r3]ip ip-prefix c permit 13.1.1.0 24 
[r3]route-policy cc permit node 10
[r3-route-policy]if-match ip-prefix c   
[r3-route-policy]apply cost-type  type-1
[r3-route-policy]q 
[r3]route-policy cc permit node 20
[r3-route-policy]q    
[r3]ospf 1
[r3-ospf-1]import-route rip route-policy cc

测试 

改变其网络类型的接口

[r4]int loopback 0

[r4-LoopBack0]ospf network-type broadcast  

 优化路由

[r2]ip ip-prefix  b  permit 2.2.2.0 24

[r2]ip ip-prefix  b  permit 12.1.1.0 24

[r2]route-policy  b permit node 10

[r2-route-policy]if-match ip-prefix b

[r2-route-policy]apply cost-type type-1

[r2]route-policy b permit node 20

[r2]ospf 1

[r2-ospf-1]import-route rip route-policy c

 [r3]ip ip-prefix  b  permit 3.3.3.0 24

[r3]ip ip-prefix  d  permit 13.1.1.0 24

[r3]route-policy d permit node 10

[r3-route-policy]if-match ip-prefix d

[r3-route-policy]apply cost-type type-1

[r3]route-policy d permit node 30

[r3]ospf 1

[r3-ospf-1]import-route rip route-policy d
