The igmp-snooping static-group suppress-dynamic-join command disables a device from forwarding IGMP Report and Leave messages that are received from a VLAN and contain a static group address to upstream Layer 3 devices configured with the static group address.
The undo igmp-snooping static-group suppress-dynamic-join command enables a device to forward IGMP Report and Leave messages that are received from a VLAN and contain a static group address to upstream Layer 3 devices configured with the static group address.
By default, a device forwards IGMP Report and Leave messages that are received from a VLAN and contain a static group address to upstream Layer 3 devices configured with the static group address.

Usage Scenario
If the upstream Layer 3 multicast device is a non-Huawei device and a static group is configured on its interface connected to the device, users cannot dynamically join or leave the multicast group. You must disable the device from sending Report and Leave messages that contain static group addresses to the Layer 3 multicast device.
This function takes effect only for IGMPv1 and IGMPv2 message and is invalid for IGMPv3 messages.
Prerequisites
IGMP snooping has been enabled globally using the igmp-snooping enable (system view) command.
Precautions
If IGMP snooping is disabled in the specified VLAN, the configuration succeeds but does not take effect until IGMP snooping is enabled in the VLAN. To enable IGMP snooping in a VLAN, run the igmp-snooping enable (VLAN view) command.
# Disable a device from forwarding IGMP Report and Leave messages that are received from VLAN 10 and contain a static group address to upstream Layer 3 devices configured with the static group address.
