  stay AS2 Run in OSPF agreement ：
Because the physical interface network segment and loopback of each router are 172.16.0.0 In segment , Therefore, only one route table can be declared ：

  The rest are the same , It's different A show of

test ,ping once

Jingxing BGP experiment ： By the reflector and the Federation BGP Horizontal segmentation of

Next test BGP The neighborhood of

  stay BGP Declare the network segment ：

Test after declaration ：

Finally, we are not announcing 192.168.1.0 and 192.168.2.0 In the case of network segment , Let it pass ：
stay R1 and R8 On the establishment of VPN, Achieve communication , By writing static routes , With Tunnel For the next communication
