General Query The MLD router regularly sends MLD general queries to query if the multicast groups contain any members. When receiving MLD general queries, the switch will forward them to all other ports in the VLAN. The receiving port will be processed: if the receiving port is not a router port yet - TP-Link T1600G-52PS TL-SG2452P | T1600G-28PSTL-SG2424P V1 User Guide - Page 137
