[AR6-bgp]peer 172.16.0.7 reflect-client 
 

目前已达到AR2--AR7无障碍通信：

（五）配置VPN隧道：

AR1:

[AR1]int t0/0/0

[AR1-Tunnel0/0/0]
[AR1-Tunnel0/0/0]source 12.1.1.1
[AR1-Tunnel0/0/0]de    
[AR1-Tunnel0/0/0]description 34.1.1.8 
 

AR8:

[AR8]int t0/0/0
[AR8-Tunnel0/0/0]ip add 10.1.1.8 24
[AR8-Tunnel0/0/0]t    
[AR8-Tunnel0/0/0]tu    
[AR8-Tunnel0/0/0]tunnel-protocol gre
[AR8-Tunnel0/0/0]source 34.1.1.8
[AR8-Tunnel0/0/0]destination 12.1.1.1
