Abstract

The present invention provides a method for assigning an IP address to a terminal, and a method and device for obtaining an IP address. The method includes: receiving a broadcast message from an online terminal, sending a response message to the online terminal according to the broadcast message, and receiving a request from the online terminal According to the request message, obtain the IP address to be assigned to the online terminal, send the detection information carrying the IP address to other member devices of the VRRP group, and receive the reply information sent by other member devices of the VRRP group, when the reply information indicates When the IP address can be used, the IP address is assigned to the online terminal. Through the solution of the present invention, when the member devices of the VRRP group share the address pool, the IP address allocated by the member selected by the online terminal will not conflict with the IP addresses allocated by other member devices of the VRRP group, and does not affect the realization of the online terminal user service , improving the reliability of the network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for assigning an IP address to a terminal, a method and a device for obtaining the IP address. Background technique [0002] With the development of network communication technology, users have higher and higher requirements for the reliability of communication network. [0003] In the prior art, the multi-level backup function of the multi-level backup network is usually used to improve the reliability of the network. The multi-level backup network may include two network devices, one as active device and the other as standby device. The active device provides support for user services, forwards service traffic, and can send service backup information to the backup device after reaching a certain time or a certain traffic threshold; the backup device receives the service backup information of the active device, and when the active device After a failure,...
