  • Page 19 Software Version sb275a05 IGMP Snooping Query Solicitation (CR00013351) Query solicitation minimises loss of multicast data after a topology change on networks that use EPSR or spanning tree (STP, RSTP, or MSTP) for loop protection and IGMP snooping. When IGMP snooping is enabled on a VLAN, and EPSR or Spanning Tree (STP, RSTP, or MSTP) changes the underlying link layer topology of that VLAN, this can interrupt multicast data flow for a significant length of time.
