What is VPNVPN (Virtual private network) is a kind of business that uses public network resources to build a private network for customers, it transmits private data on the public Internet and achieves the security level of private network through packet and encrypted transmission of network data.It has two characteristics. First, virtual. It does not need to set up a special network for the physical connection, the use of public network resources, as long as there is connectivity to the public

Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is implemented, whether the PE

As we all know, due to the shortage of public IP addresses, we usually use reserved IP addresses as internal IP addresses when establishing a LAN. These reserved IP addresses cannot be routed over the Internet, therefore, normally, we cannot directly access hosts in the LAN through the Internet. To achieve this goal, we need to use VPN tunneling technology.-Generally, the VPN gateway adopts a dual-network c
