Problems solved by technology

[0004] However, during actual operation, if traffic is transmitted between different VPNs, especially when there are active and standby links, traffic packet loss is prone to occur.

Abstract

The invention provides a route updating method, device and equipment and a medium, and the method is applied to public network edge side equipment of a virtual private network VPN, and comprises the steps: receiving service route information transmitted by public network edge side equipment at an opposite end, and enabling the service route information to carry a public network next hop; judging whether the route reaching the next hop of the public network is valid or not; and updating the VPN route forwarding table according to the judgment result. By applying the embodiment of the invention,when flow transmission is carried out between two VPNs connected through a public network, the flow packet loss rate can be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a route updating method, device and equipment, and a medium. Background technique [0002] Virtual Private Network (Virtual Private Network) is a secure private virtual network temporarily established on the Internet, which can bring huge benefits to users in terms of reducing usage costs, increasing scalability, and enhancing security. [0003] After the VPN is generated, in order to connect different VPNs through the public network (hereinafter referred to as the public network) (compared to the public network, the VPN is a private network), such as in order to communicate with each other through the public network between VPN1 and VPN2, you can use the same VPN1 and VPN2. The IP address of the VPN routing and forwarding table (VRF) is used to realize the routing isolation between different VPNs, and each VRF will have a relatively independent routin...
