NOTE:
The
reset igmp-snooping group
command works only on an IGMP snooping–enabled VLAN, but
not on 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.

Network requirements
•
, Router A connects to the multicast source through GigabitEthernet 1/0/2
and to Switch A through GigabitEthernet 1/0/1.
•
IGMPv2 runs on Router A, IGMPv2 snooping runs on Switch A, and Router A will act as the IGMP
querier on the subnet.
•
Receivers, Host A and Host B, are attached to Switch A, and they can receive multicast traffic
addressed to multicast group 224.1.1.1 only.
•
Multicast data for group 224.1.1.1 can be forwarded through GigabitEthernet 1/0/3 and
GigabitEthernet 1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop
receiving multicast data.
