Disclosed are a two-stage duplication method and apparatus for a multicast message, and a storage medium. The method comprises: obtaining an address of a layer-2 multicast duplication information table by using multicast descriptor information of a to-be-duplicated multicast message; checking the layer-2 multicast duplication information table by using the address of the layer-2 multicast duplication information table to obtain layer-3 multicast duplication information, and duplicating the to-be-duplicated multicast message according to the obtained layer-3 multicast duplication information until layer-3 multicast duplication is completed; and checking the layer-2 multicast duplication information table by using the address of the layer-2 multicast duplication information table to obtain layer-2 multicast duplication information, and duplicating the to-be-duplicated multicast message according to the obtained layer-2 multicast duplication information until layer-2 multicast duplication is completed. |
