OSPF分流实验

一、配置IP
二、将R1~4建一个OSPF1，R3 R4 R5建OSPF2，R3 R4 R7建一个OSPF3
[r1]ospf 1 router-id 1.1.1.1
[r1-ospf-1]a 0
[r1-ospf-1-area-0.0.0.0]network 14.1.1.1 0.0.0.0
[r1-ospf-1-area-0.0.0.0]network 14.1.2.1 0.0.0.0
[r1-ospf-1-area-0.0.0.0]network 10.1.1.1 0.0.0.0
[r1-ospf-1-area-0.0.0.0]network 10.1.2.1 0.0.0.0

[r3]ospf 2
[r3-ospf-2]a 0
[r3-ospf-2-area-0.0.0.0]network 24.1.1.1 0.0.0.0
[r3]ospf 3 router-id 3.3.3.3
[r3-ospf-3]a 0
[r3-ospf-3-area-0.0.0.0]net 24.1.2.1 0.0.0.0

[r6]ospf 3 router-id 6.6.6.6
[r6-ospf-3]a 0
[r6-ospf-3-area-0.0.0.0]net 10.1.6.1 0.0.0.0
[r6-ospf-3-area-0.0.0.0]net 10.2.6.1 0.0.0.0
[r6-ospf-3-area-0.0.0.0]net 24.1.2.2 0.0.0.0
[r6-ospf-3-area-0.0.0.0]net 24.1.4.2 0.0.0.0
三、重分布后，R3上增大R4cost,R4相反

[r3]ospf 2
[r3-ospf-2]import-route ospf 1
[r3-ospf-2]import-route ospf 3
[r3]ospf 3
[r3-ospf-3]import-route ospf 1
[r3-ospf-3]import-route ospf 2
R4同理

测试连通性
