第一步配置IP地址
R1:
[R1]int Serial 4/0/0
[R1-Serial4/0/0]ip address 12.0.0.1 24
[R1-Serial4/0/0]int g 0/0/0
[R1-GigabitEthernet0/0/0]ip address 14.0.0.1 24[R1-GigabitEthernet0/0/0]int l0
[R1-LoopBack0]ip address 1.1.1.1 24
R2,R3,R4配置相同
第二步：划分rip和ospf
R1
[R1]rip 1
[R1-rip-1]version 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
[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 23.0.0.0 0.0.0.255
R3
[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 23.0.0.0 0.0.0.255
[R3-ospf-1-area-0.0.0.0]network 3.3.3.0 0.0.0.255
[R3-ospf-1-area-0.0.0.0]network 34.0.0.0 0.0.0.255
R4
[R4]rip 1
[R4-rip-1]version 2
[R4-rip-1]network 14.0.0.0
[R4-rip-1]q
[R4]ospf 1 router-id 4.4.4.4
[R4-ospf-1]area 0
[R4-ospf-1-area-0.0.0.0]network 34.0.0.0 0.0.0.255
[R4-ospf-1-area-0.0.0.0]network 4.4.4.0 0.0.0.255
第三步：重发布
R2
[R2]rip 1
[R2-rip-1]import-route ospf 1
[R2-rip-1]ospf 1
[R2-ospf-1]import-route rip 1
R4
[R4]rip 1
[R4-rip-1]import-route ospf 1
[R4-rip-1]q
[R4]ospf 1
[R4-ospf-1]import-route rip 1
第四步：改接口
[R3-LoopBacke]ospf network-type broadcast
[R4-LoopBacke]ospf network-type broadcast
第五步：写策略
R2
[R2]ip ip-prefix 1 permit 4.4.4.0 24
[R2]route-policy celve permit node 10
[R2-route-policy]apply cost +1
[R2]route-policy celve permit node 20
[R2]ip ip-prefix 1 permit 34.0.0.0 24
[R2]route-policy celve permit node 15
[R2-route-policy]apply cost +10
R4
[R4]ip ip-prefix 1 permit 2.2.2.0 24
[R4]route-policy celve deny node 10
Info: New Sequence of this List.
[R4-route-policy]if-match ip-prefix 1
[R4-route-policy]q
[R4]route-policy celve permit node 20
Info: New Sequence of this List
[R4-route-policy]qR4]ospf 1
[R4-ospf-1]import-route rip1 route-policy celve
[R4]ip ip-prefix 1 permit 23.0.0.0 24
[R4]route-policy celve permit node 15
[R4-route-policy]apply cost +10
[R4-ospf-1]import-route rip1 route-policy celve
