文章详细描述了在R2路由器上配置RIP和OSPF协议的过程，包括网络地址和路由重发布。同时，通过路由策略对路由信息进行修改，调整路由的优先级和成本，确保最优路径的选择。在R3路由器上也执行了类似的操作，验证了路径的优化效果。

R2路由

先进行左边rip的配置右边ospf配置（仅以R2为例）

[r2]rip
[r2-rip-1]version 2
[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 24.1.1.1 0.0.0.0

这里使用双向重发布

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

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

使用路由策略修改路由信息

[r2]ip ip-prefix 50 permit 5.5.5.0 24
[r2]ip ip-prefix 30 permit 3.3.3.0 24
[r2]ip ip-prefix 34 permit 34.1.1.0 24

[r2]route-policy aaa permit node 10

[r2-route-policy]if-match ip-prefix 50

[r2-route-policy]apply preference 151

[r2]rip

[r2-rip-1]preference route-policy aaa

[r2]route-policy aaa permit node 20

[r2-route-policy]if-match ip-prefix 30
[r2-route-policy]apply cost 3

[r2]route-policy aaa permit node 30

[r2-route-policy]if-match ip-prefix 34

[r2-route-policy]apply cost 3

[r2]route-policy aa permit node 40

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

[r2]ip ip-prefix 12 permit 12.1.1.0 24
[r2]ip ip-prefix 21 permit 2.2.2.0 24

[r2]route-policy bbb permit node 10

[r2-route-policy]if-match ip-prefix 21

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

[r2]route-policy bbb permit node 20

[r2-route-policy]if-match ip-prefix 12

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

[r2]route-policy bbb permit node 30

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

R3：使用路由策略修改路由信息

[r3]ip ip-prefix 50 permit 5.5.5.0 24
[r3]ip ip-prefix 20 permit 2.2.2.0 24
[r3]ip ip-prefix 24 permit 24.1.1.0 24

[r3]route-policy ccc permit node 10

[r3-route-policy]if-match ip-prefix 50
[r3-route-policy]apply preference 151

[r3]rip

[r3-rip-1]preference route-policy ccc

[r3]route-policy ccc permit node 20

[r3-route-policy]if-match ip-prefix 20

[r3-route-policy]apply cost 3

[r3]route-policy ccc permit node 30

[r3-route-policy]if-match ip-prefix 24

[r3-route-policy]apply cost 3

[r3]route-policy ccc permit node 40

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

[r3]int LoopBack 0
[r3-LoopBack0]ospf network-type broadcast

[r3]ip ip-prefix dd permit 13.1.1.0 24

[r3]route-policy dd permit node 10

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

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

[r3]route-policy dd permit node 20

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

这里随便查看一下是否为优路径
