Abstract

The present invention provides a multicast packet processing method and a network device. The multicast packet processing method comprises the steps that the network device obtains device-level number information and obtains the neighbor network device information of the network device according to the device-level number information; the network device obtains a multicast replication control mark in a multicast packet, and the multicast replication control mark is used for identifying the multicast path of the multicast packet; the network device copies the multicast packet to the neighbor network device of the network device in the multicast path according to the multicast replication control mark and the neighbor network device information. According to the embodiment of the invention, the problem that the network device needs the multicast entries of a multicast group to copy and forward a packet, each of the multicast entries needs to be stored in the network device and occupies the multicast resource of the network device, and the multicast resource requirement of the network device is high.

Description

technical field [0001] The invention relates to network technology, in particular to a multicast message processing method and network equipment. Background technique [0002] Data center network generally adopts such as figure 1 The shown fat tree architecture implements Fabric networking. In the fat tree architecture, switching devices are arranged in layers and converged step by step. The fat tree structure generally has a two-layer or three-layer structure, and sometimes a controller (Controller) may also be provided to manage and configure each switching device in the fat tree structure. Fabric specifically refers to a "combined device" formed by connecting multiple switching devices supporting an Intelligent Resilient Framework (English: Intelligent Resilient Framework, IRF for short). [0003] There is often a need for multicast services in the data center network. The multicast forwarding method of the multicast service in the Fabric is the same as that in the trad...
