R3配置

    [r3]rip
    [r3-rip-1]version 2
    [r3-rip-1]network 13.0.0.0
    [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

R4

    [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 24.0.0.2 0.0.0.0

R4路由信息

R2 R3进行双向重发布
R2

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

R3

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

R1路由信息

 

优化2.2.2.0 24

    [r3]ip ip-prefix cc permit 2.2.2.0 24

    [r3]route-policy aa permit node 10

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

    [r3-route-policy]apply cost 10

优化12.0.0.0 24

    [r3]ip ip-prefix cc permit 12.0.0.0 24

    [r3]route-policy aa permit node 20

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

    [r3-route-policy]apply cost 10

在OSPF中调用路由策略：

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

优化13.0.0.0 24

    [r2]ip ip-prefix bb permit 13.0.0.0 24

    [r2]route-policy aa permit node 10

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

    [r2-route-policy]apply cost 10

在OSPF中调用路由策略

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