路由策略实验

1. 实验拓扑

3. 启rip，ospf协议

R1：

[r1]rip 1

[r1-rip-1]ver 2

[r1-rip-1]network 1.0.0.0

[r1-rip-1]network 12.0.0.0

[r1-rip-1]network 13.0.0.0

R2：

[r2]rip 1

[r2-rip-1]ver 2

[r2-rip-1]network 12.0.0.0

[r2-rip-1]network 2.0.0.0

[r2-rip-1]q

[r2]ospf 1 rou

[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：

[r3]rip 1

[r3-rip-1]ver 2

[r3-rip-1]network 13.0.0.0

[r3-rip-1]q

[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：

[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 24.1.1.2 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 45.1.1.1 0.0.0.0

R5：

[r5]ospf 1 router-id 5.5.5.5

[r5-ospf-1]area 0

[r5-ospf-1-area-0.0.0.0]network 5.5.5.5 0.0.0.0

[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

R6：

[r6]ospf 1 router-id 6.6.6.6

[r6-ospf-1]area 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 56.1.1.2 0.0.0.0

[r6-ospf-1-area-0.0.0.0]network 67.1.1.1 0.0.0.0

R7：

[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

4. 在R2，R3，R7上进行重发布

R7：

[r7]ospf 1

[r7-ospf-1]import-route direct

R2：

[r2]rip 1

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

[r2-rip-1]q

[r2]ospf 1

[r2-ospf-1]import-route rip

R3：

[r3]rip 1

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

[r3-rip-1]q

[r3]ospf 1

[r3-ospf-1]import-route rip

[r3-LoopBack0]ospf network-type broadcast

解决R7 环回重发布产生的环路

R2：

[r2]ip ip-prefix a permit 7.7.7.0 24

[r2]route-policy quhuan permit node 10

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

[r2-route-policy]apply preference 151

[r2-ospf-1]preference route-policy quhuan

R3：

[r3]ip ip-prefix a permit 7.7.7.0 24

[r3]route-policy quhuan permit node 10

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

[r3-route-policy]apply preference 151

[r3-rip-1]preference route-policy quhuan

将给R1的rip增加度量

R2：

[r2]ip ip-prefix qq permit 3.3.3.0 24

[r2]ip ip-prefix qq permit 34.1.1.0 24

[r2]int g0/0/0

[r2-GigabitEthernet0/0/0]rip metricout ip-prefix qq 2

R3：

[r3]ip ip-prefix qq permit 24.1.1.0 24

[r3]int g0/0/0

将R2环回、12网段和13网段改为类型1

[r2]ip ip-prefix ww permit 12.1.1.0 24

[r2]ip ip-prefix ww permit 2.2.2.0 24

[r2]route-policy fuzai permit node 10

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

[r2-route-policy]apply cost-type type-1

[r2-route-policy]q

[r2]route-policy fuzai permit node 20

[r2-route-policy]q

[r2]ospf 1

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

R3：

[r3]ip ip-prefix aa permit 13.1.1.0 24

[r3]route-policy fuzai permit node 10

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

[r3-route-policy]apply cost-type type-1

[r3-route-policy]q

[r3]route-policy fuzai permit node 20

[r3-route-policy]q

[r3]ospf 1

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