  peer 3.3.3.3 next-hop-local
  peer 4.4.4.4 next-hop-local

3、R3的配置

undo ter mo

4、R4的配置

undo ter mo
sys
sysname R4
user-interface console 0
idle-timeout 0 0
int loop 0
ip add 4.4.4.4 24
int g0/0/0
ip add 192.168.34.4 24
int g0/0/1
ip add 192.168.45.4 24
ospf router-id 4.4.4.4

5、R5的配置

undo ter mo
sys
sysname R5
user-interface console 0
idle-timeout 0 0
int loop 0
ip add 5.5.5.5 24
int g0/0/1
ip add 192.168.45.5 24

四、实验结果

1、R1上查看BGP路由表信息

2、R1测试与R5的连通性，ping -a 1.1.1.1 5.5.5.5
