[R1]rip
[R1-rip-1]version 2
[R1-rip-1]network 14.0.0.0 
[R1-rip-1]network 15.0.0.0

[R2]ospf 1
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 12.1.1.0 0.255.255.255
[R2]isis 1
[R2-isis-1]network-entity 49.0023.0000.0000.0002.00
[R2-isis-1]is-level level-1
[R2]interface GigabitEthernet 0/0/1
[R2-GigabitEthernet0/0/1]isis enable 1

[R3]isis 1
[R3-isis-1]network-entity 49.0023.0000.0000.0003.00
[R3-isis-1]is-level level-1
[R3]interface GigabitEthernet 0/0/1
[R3-GigabitEthernet0/0/1]isis enable 1
[R3]interface LoopBack 0
[R3-LoopBack0]isis enable 1

[R4]rip 1   
[R4-rip-1]version 2
[R4-rip-1]network 4.0.0.0
[R4-rip-1]network 14.0.0.0

[R5]rip 1   
[R5-rip-1]version 2
[R5-rip-1]network 5.0.0.0
[R5-rip-1]network 15.0.0.0

（2）R1配置感兴趣路由并引入路由策略

[R1]acl  2000
[R1-acl-basic-2000]rule permit source 4.4.4.4 0.0.0.0
[R1]acl 2001
[R1-acl-basic-2001]rule permit source 5.5.5.5 0.0.0.0

[R1]route-policy dsrw.com permit node 10
[R1-route-policy]if-match acl 2000
[R1-route-policy]apply tag 10

[R1]route-policy dsrw.com permit node 20
[R1-route-policy]if-match acl 2001                   
[R1-route-policy]apply tag 20       

[R1]ospf 1
[R1-ospf-1]import-route rip route-policy dsrw.com
[R1]rip 1
[R1-rip-1]import-route ospf 1

（3）R2配置感兴趣路由并引入路由策略

[R2]route-policy dsrw.com deny node 10
[R2-route-policy]if-match tag 20
[R2]route-policy dsrw.com permit node 20
[R2]isis 1
[R2-isis-1]import-route ospf 1 level-1 route-policy dsrw.com
[R2]ospf 1
[R2-ospf-1]import-route isis 1
