1.搭建拓扑

2.IP配置

R1 
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 10.0.12.1 24
[r1-GigabitEthernet0/0/0]int loop 0
[r1-LoopBack0] ip add 1.1.1.1 24

R2
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 10.0.12.2 24
[r2-GigabitEthernet0/0/0]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 172.16.23.2 24
[r2-GigabitEthernet0/0/1]int g0/0/2
[r2-GigabitEthernet0/0/2]ip add 172.16.25.2 24
[r2-GigabitEthernet0/0/2]int loop 0
[r2-LoopBack0] ip add 172.16.0.2 24
[r2-LoopBack0]int loop 1
[r2-LoopBack1]ip add 172.16.2.1

R3

 R4

R5

R6

R7 

R8 

3.ospf

[R2]ospf 2
[R2-ospf-2]area 0
[R2-ospf-2-area 0]nework 172.16.0.0 0.0.255.255 

4. 把AS2的用户网段更改为BROADCAST

[R2] intface loopback 1
[R2-LoopBack1]ospf network-type broadcast

5.建立bgp邻居关系
