2.进行OSPF和RIP宣告

[r1]rip 1
[r1-rip-1]ver 2
[r1-rip-1]network 12.0.0.0
[r1-rip-1]network 13.0.0.0
[r1-rip-1]network 1.0.0.0
[r2]rip 1
[r2-rip-1]ver 2 
[r2-rip-1]network 12.0.0.0
[r2-rip-1]network 2.0.0.0
[r3]rip 1
[r3-rip-1]ver 2
[r3-rip-1]network 13.0.0.0 

[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
[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
[r3-ospf-1-area-0.0.0.0]network 34.1.1.1 0.0.0.0
[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 34.1.1.2 0.0.0.0
[r4-ospf-1-area-0.0.0.0]network 24.1.1.2 0.0.0
[r4-ospf-1-area-0.0.0.0]network 45.1.1.1 0.0.0.0
[r5]ospf 1 router-id 5.5.5.5 
[r5-ospf-1]area 0
[r5-ospf-1-area-0.0.0.0]network 45.1.1.2 0.0.0.0
[r5-ospf-1-area-0.0.0.0]network 56.1.1.1 0.0.0.0
[r5-ospf-1-area-0.0.0.0]network 5.5.5.5 0.0.0.0
[r6]ospf 1 router-id 6.6.6.6
[r6-ospf-1]area 0
[r6-ospf-1-area-0.0.0.0]network 56.1.1.2 0.0.0.0
[r6-ospf-1-area-0.0.0.0]network 6.6.6.6 0.0.0.0
[r6-ospf-1-area-0.0.0.0]network 67.1.1.1 0.0.0.0
[r7]ospf 1 router-id 7.7.7.7
[r7-ospf-1]area 0
[r7-ospf-1-area-0.0.0.0]network 67.1.1.2 0.0.0.0

（测试）

3.解决环路问题

（1）形成环路
（导入R7的直连路由）
[r7]ospf 1
[r7-ospf-1]import-route direct 

（测试）

[r2]ospf 1
[r2-ospf-1]import-route rip
[r2]rip 1
[r2-rip-1]import-route ospf 1
[r3]ospf 1
[r3-ospf-1]import-route rip
[r3]rip 1
[r3-rip-1]import-route ospf 1

（查看）




（形成了环路）

（R5）

 
（形成等开销负载均衡）

（2）解决环路
（修改RIP优先级，让路由去不了R3）

[r3]acl 2000
[r3-acl-basic-2000]rule permit source 7.7.7.0 0
[r3]route-policy a permit node 10
Info: New Sequence of this List.
[r3-route-policy]if-match acl 2000
[r3-route-policy]apply preference 151
[r3]rip 1
[r3-rip-1]preference route-policy a

（查看）

（3）测试

4.解决R2和R3的环回

[r3]int lo0
[r3-LoopBack0]ip add 3.3.3.3 32
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1] shutdown
[r1-GigabitEthernet0/0/1]undo shutdown
[r3]int g0/0/1
[r3-GigabitEthernet0/0/1] shutdown
[r3-GigabitEthernet0/0/1]undo shutdown

（查看）

[r3]acl 2001
[r3-acl-basic-2001]rule permit source 2.2.2.0 0
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]rip metricout 2001 2

（查看）

5.修改偏移列表

[r2]acl 2001
[r2-acl-basic-2001]rule permit source 3.3.3.3 0
[r2-acl-basic-2001]rule permit source 34.1.1.0 0
[r2]int g0/0/0
[r2-GigabitEtherent0/0/0]rip metricout 2001 2
[r3]acl 2001
[r3-acl-basic-2001]rule permit source 24.1.1.0 0

（查看）

 

 6.修改类型

[r2]ip ip-perfix q permit 12.1.1.0 24
[r2]ip ip-perfix q permit 2.2.2.0 24
[r2]route-pilcy w permit node 10
[r2-route-policy]if-match ip-perfix q
[r2-route-policy]apply cost-type type-1
[r2]route-policy w permit node 20
[r2]ospf 1
[r2-ospf-1]import-route rip route-policy w

（查看）

[r3]ip ip-prefix q permit 13.1.1.0 24
[r3]route-policy w permit node 10
[r3-route-policy]if-match ip-prefix q
[r3-route-policy]apply cost-type type-1
[r3]route-policy w permit node 20
[r3]ospf 1
[r3-ospf-1]import-route rip route-policy w
