The present invention is applicable to the field of communications, and provides a multicast processing method, apparatus and system. The method includes: receiving, by a VTEP, configuration information sent by a management layer; receiving, by the VTEP, a multicast packet sent by a VM managed by the VTEP; when performing VXLAN encapsulation on the multicast packet after determining that the VM matches the VM tenant identifier, encapsulating, according to a mapping relationship between the VM multicast address and a multicast address on a layer 3 network, a source address and a destination address of the multicast packet into the multicast address on the layer 3 network, and encapsulating, according to a mapping relationship between a VM multicast source address and a layer 3 network multicast source address, a VXLAN source address of the multicast packet into the layer 3 network multicast source address; and sending an encapsulated multicast packet to the layer 3 network. Technical solutions provided in the present invention have an advantage of enabling a VM to correctly select a multicast source. |
