The present invention provides a method for controlling and managing a multicast group in a subnet, including: a multicast group configuration method on a router and a method for synchronizing multicast group configuration between a router and a switching device; wherein, the group on the router The configuration method of the multicast group is as follows: the router learns the multicast group to be created in the subnet and the members of each multicast group by loading a configuration file of a multicast group and multicast group members, and completes the configuration of the router itself according to this configuration information. The configuration of the router and the switching device synchronous multicast group configuration is as follows: the router and the switch use multicast messages to exchange relevant information, and the router and the switch exchange messages. The present invention can complete the technical problem of management and configuration of the multicast group members in the subnet only by configuring on the router, simplifies the management and configuration of the switch multicast group, and simplifies the method for the host to join the multicast group.
Description
technical field [0001] The invention relates to the technical field of router and switch multicast group management and control, in particular to a method for controlling and managing multicast group members in a subnet. Background technique [0002] Multicast technology is a transmission mode of IP network data, and has its special advantages in some scenarios (such as point-to-multipoint communication scenarios). When multiple users in the network need to obtain specific data, the data source sends the information only once. When the information passes through a router or switch, the router or switch forwards or distributes the information according to the multicast configuration to ensure that multiple users can receive the information. At the same time, in order to ensure that the multicast data is transmitted only on the necessary path, it is necessary to configure routers and switches. [0003] At present, the IGMP protocol is mainly used for multicast group manageme...
