Problems solved by technology

[0006] However, the DHCP servers deployed in some VPN remote networks do not support the identification and analysis of OPTION82 options. In this scenario, using this conventional method cannot accomplish the purpose of downlink unicast to specified users.

Embodiment Construction

[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0061] First, the data exchanged between the user side and the network side in the L3VPN service is introduced.

[0062] Network data is divided into two categories: user business-related data streams such as access to browsers and videos. And a signaling flow for configuring user access network parameters. The signaling flow is mainly the flow of information between the client and the server. From a functional point of view, the signaling flow has the following types:

[0063] (1) The broadcast request message sent by the DHCP client to the DHCP server requests the configuration of various network parameters from the DHCP server, including packets in the formats of DHCP DISCOVER and DHCP REQUEST. DISCOVERY belongs to the discovery stage: it is used to find the specified link DHCP server; REQUEST belongs to the request stage, and confirms t...

Abstract

The invention discloses a message processing method based on a DHCP RELAY protocol and a relay device. The method relates to the field of DHCP RELAY, and comprises the steps of generating an interfaceinformation table for recording a mapping relationship between an interface VLAN ID and an interface index, and a forwarding domain information table for recording a mapping relationship between theinterface VLAN ID and an interface virtual routing forwarding VRF ID; analyzing a uplink request message of a client, obtaining user attribute information, storing or updating the user attribute information to a local MAC information storage table to establish a mapping relationship between the MAC address of the client and the interface VLAN ID, inserting the user attribute information into the uplink request message, and sending the user attribute information to the server; analyzing a downlink protocol message responded to by the server, and sending the downlink protocol message to the client in a unicast manner from a specified output interface based on the MAC information storage table, the interface information table and the forwarding domain information table. According to the invention, the impact of downlink protocol message broadcasting and flooding can be avoided, and the network stability and security are enhanced.

Description

technical field [0001] The invention relates to the field of DHCP RELAY, in particular to a message processing method and relay equipment based on the DHCP RELAY protocol. Background technique [0002] With the large-scale popularization of PON (Passive Optical Network, Passive Optical Network) access to optical networks, end users will frequently use IPTV (Internet Protocol Television, Interactive Network Television) TV, VOIP (Voice over Internet Protocol, VoIP) voice and other emerging services. The way to obtain an IP address has changed a lot. DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) access and PPPOE (Point-to-Point Protocol Over Ethernet, Ethernet-based point-to-point communication protocol) dial-up have become mainstream access. into technology. [0003] On the other hand, due to the promotion of operator's network flat management requirements, the DHCP server is usually deployed in a VPN (Virtual Private Network, virtual privat...
