The present application provides a multicast message sending method, related devices and network equipment, which are applied to the network board of the network equipment of the switching network. The network equipment also includes a plurality of line card boards, and each line card board includes at least A forwarding chip; receiving the message sent by the line card board; when the message is a multicast message, parsing the chip identification information of the destination forwarding chip from the multicast message; based on the chip identification information and the multicast Table, determining the port identification information of the outgoing port corresponding to the destination forwarding chip in the network board; copying the multicast message, and passing the copied message of the multicast message through the determined The outgoing port corresponding to the port identification information is sent to the line card board to which the destination forwarding chip belongs, and the line card board to which the destination forwarding chip belongs sends the copied message to the destination forwarding chip. By adopting the above method, the problem of multi-duplication of multicast packets in the prior art is solved.
Description
technical field [0001] The present application relates to the field of computer communication technologies, and in particular, to a method for sending multicast packets, related apparatuses, and network equipment. Background technique [0002] When the switching network sends multicast packets, it usually performs on-demand multicast based on the multicast ID. Since the switching network chip is not a forwarding chip, the multicast table is usually very small, which causes the multicast packets to be folded on the switching network. . For example, the specification of the multicast table in the switching network is 2K. In this way, the multicast packets with the multicast ID of 1 and 2K+1 will locate the same multicast entry of 1 when querying the multicast table. However, when the destination ports of the multicast packets with the multicast IDs of 1 and 2K+1 are different, the prior art can only use the method of union, that is, the multicast IDs of 1 and 2K+1 are respect...
