Abstract

The invention provides a communication method and device. The method is applied to first UP equipment. The method comprises the following steps: receiving a multicast joining message sent by a host, wherein the multicast joining message comprises an identifier of a first interface and a multicast group address; generating a first multicast group table item at the first interface according to the identifier of the first interface and the multicast group address; when the first UP equipment is the main equipment, acquiring backup group information, wherein the backup group information comprises interface information of standby equipment; according to the interface information of the standby device, sending a first route-refresh message to a second UP device where an interface indicated by the interface information is located, wherein the first route-refresh message comprises the name of a backup group, an addition mark and a multicast addition message, so that the second UP device obtains the backup group information and determines a second interface, and generating a second multicast group table item at the second interface according to the adding mark and the multicast adding message.

Description

Technical field [0001] The present application relates to the field of communication technologies, and more particularly to a communication method and apparatus. Background technique [0002] In the traditional integrated broadband remote access server (English: Roadband Remote Access Server, the multi-machine backup function, the multi-machine backup function provides a virtual service redundancy protocol (English: Virtual ServicesRedundancy Protocol, referred to as: vsrp) Network reliability solution for device levels. It can ensure that the user's business data is uninterruptible when the network device is faulty. Among them, the establishment of a multi-machine backup channel is key technologies. [0003] The multi-machine backup of the multi-machine backup channel is required to perform status data and the synchronization of the business data. The multi-machine backup channel is created using a transfer control protocol (English: Transmission Control Protocol, referred to as...
