Abstract

The present invention provides a method and a device for preventing the medium access control address to be deceived. The present invention comprises: Step one, the access node of the network automatically acquires the medium access control address of the broadband network gateway; Step two, the access node configures the medium access control address acquired from the broadband network gateway into the static medium access control address table of the access node or the visit control list. The present invention solves the security problem of the broadband network gateway MAC address deceit, and guarantees the automatic configuration of the broadband network gateway MAC address, and the security, the flexibility and the extendibility of the broadband access network can be enhanced.

Description

technical field

[0001] The present invention relates to the technical field of network communication, in particular to a method and device for preventing MAC (Media Access Control, Media Access Control) address spoofing in a network. Background technique

[0002] At present, the broadband access network is developing towards the broadband access network based on Ethernet aggregation, and its architecture includes the following parts: user network, access node (Access Node (AN)), Ethernet aggregation network and broadband network gateway ( Broadband Network Gateway (BNG)). Among them, the access node completes the multi-form access of users, such as DSLAM (Digital Subscriber Line Access Multiplexer), etc.; the broadband network gateway refers to the IP (Internet Protocol Internet Protocol) that can apply bandwidth and QoS (quality of service, quality of service) strategies. ) edge routers, such as BRAS (Broadband Remote Access Server, Broadband Remote Access Server) and serv...
