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

connection to the corporate network, which is provided by the corporate network to the target tunnel server route for encapsulating load data. Most people mistakenly believe that a VPN can only use a dial-up connection. In fact, the VPN as long as the Internet to support IP. Some clients, such as the home PC, can establish IP transmissions by connecting to the Internet by using dial-up methods. This is onl

Network knowledge Review-VPN Virtual Private Network (VPN) refers to the technology for establishing a private Network on a public Network. It is called virtual network, mainly because the connection between any two nodes of the VPN network does not have the end-to-end physical link required by the traditional private network, but is built on the network platform

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

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
