  NOTE: 
•  The  reset igmp-snooping group  command works only on an IGMP snooping–enabled VLAN, but no
t
in a VLAN with IGMP enabled on its VLAN interface.  
•   The  reset igmp-snooping group  command cannot remove the static group entries of IGMP snooping 
groups.

2 2 5 .1.1.1.  
All the receivers run IGMPv2, and all the switches run IGMPv2 snooping. Switch A, which is close to the 
multicast sources, is chosen as the IGMP snooping querier. 
To prevent flooding of unknown multicast traffic within the VLAN, be sure to configure all the switches to 
drop unknown multicast data packets.  
Because a switch does not enlist a port that has heard an IGMP query with a...
