A first switch flashes an FDB upon receiving an FDB flash frame and then floods a multicast group join query message (QRY1). A terminal sends a group join message (RP1) back to the first switch. A second switch, a third switch and the first switch receive RP1 and perform IGMP/MLD snooping, respectively.
