interface GigabitEthernet3/0/0
ip address 14.0.45.4 255.255.255.0 

R5

interface GigabitEthernet0/0/0
ip address 14.0.45.5 255.255.255.0

ip address 10.1.6.1 255.255.255.0 
interface LoopBack2
ip address 10.2.6.6 255.255.255.0

三、OSPF配置

R1

ospf 1 router-id 1.1.1.1 
area 0.0.0.1 
network 10.1.1.0 0.0.0.255 
network 10.2.1.0 0.0.0.255 
network 14.1.0.0 0.0.255.255

R2

ospf 1 router-id 2.2.2.2 
area 0.0.0.1 
network 10.1.2.0 0.0.0.255 
network 10.2.2.0 0.0.0.255 
network 14.1.0.0 0.0.255.255

R3

ospf 1 router-id 3.3.3.3 
area 0.0.0.1 
network 14.1.0.0 0.0.255.255 
ospf 2 router-id 3.3.3.3 
area 0.0.0.0 
network 14.0.0.0 0.0.255.255

R4

ospf 1 router-id 4.4.4.4 
area 0.0.0.1 
network 14.1.0.0 0.0.255.255 
ospf 2 router-id 4.4.4.4 
area 0.0.0.0 
network 14.0.0.0 0.0.255.255 

R5

ospf 1 router-id 5.5.5.5 
area 0.0.0.0 
network 10.1.5.0 0.0.0.255 
network 10.2.5.0 0.0.0.255 
network 14.0.0.0 0.0.255.255

R6

ospf 1 router-id 6.6.6.6 
area 0.0.0.0 
network 10.1.6.0 0.0.0.255 
network 10.2.6.0 0.0.0.255 
network 14.0.0.0 0.0.255.255

四、进行重发布

1、R3、R4进行如下配置

ip ip-prefix a1 permit 10.2.1.0 24
ip ip-prefix a2 permit 10.2.2.0 24
ip ip-prefix a3 permit 10.2.5.0 24
ip ip-prefix a4 permit 10.2.6.0 24

2、备份路由配置

[Rx]route-policy 1 permit node 10
[Rx-route-policy]if-match ip-prefix a1
[Rx-route-policy]apply cost 10
[Rx-route-policy]q
[Rx]route-policy 1 permit node 20

3、重发布调用

[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]import-route ospf 2 route-policy 3
[R3-ospf-1]import-route ospf 2 route-policy 4
[R3]ospf 2 router-id 3.3.3.3
[R3-ospf-1]import-route ospf 1 route-policy 1
[R3-ospf-1]import-route ospf 1 route-policy 2
