Problems solved by technology

[0005] However, the cleaned traffic sent by the cleaning server 103 hits the flow specification rule, so the border routing device will resend the cleaned traffic sent by the cleaning server 103 to the cleaning server 103, causing the traffic to form a loop, and the user terminal 104 cannot receive it correctly. to the cleaned flow

Abstract

Embodiments of the present invention provide a traffic cleaning method and device, and a first border routing device. The method includes: establishing a tunnel with a first interface as a source node and the second interface as a tail node, where the first interface is an interface learned through BGP and used for sending packets to the second border routing device ; Forward the traffic received by the interface that does not establish a BGP neighbor relationship to the cleaning server through the tunnel for traffic cleaning. By establishing a tunnel between the first border routing device and the second border routing device, the first border routing device and the second border routing device have two different routes, the route learned through BGP and the established tunnel. , and transmit the traffic received by different types of interfaces with different routes, so that the border routing device can transmit the cleaned traffic and the uncleaned traffic with different routes, avoiding the formation of loops in the BGP network.

Description

technical field [0001] The present invention relates to the field of information technology, and in particular, to a traffic cleaning method, device and first border routing device. Background technique [0002] Flow Specification (Flowspec) technology can be used to filter and inspect illegal traffic in BGP (Border Gateway Protocol) networks, thereby mitigating DOS (Denial of Service, denial of service) attacks, DDOS (Distributed Denial of Service) The impact of illegal attacks such as attacks on the BGP network. [0003] Exemplarily, as figure 1 As shown, the BGP network may include a flow specification controller (hereinafter referred to as a controller) 101 and a plurality of flow specification border routing devices (hereinafter referred to as border routing devices). For the convenience of description, figure 1 The four border routing devices are respectively denoted as border routing device 1, border routing device 2, border routing device 3 and border routing devi...
