Parameters
| Parameter | Description | Value |
|---|---|---|
| vpn-instance vpn-instance-name | Deletes dynamic IGMP entries in a specified VPN instance. | The value must be an existing VPN instance name. |
| all-instance | Deletes dynamic IGMP entries in all instances. | - |
| all | The first all deletes dynamic IGMP entries on all interfaces. The second all deletes all dynamic IGMP entries on a specified interface. | - |
| interface interface-type interface-number | Deletes dynamic IGMP entries on a specified interface. | - |

| source-mask-length | Specifies the mask length of a multicast source address. | The value is an integer that ranges from 0 to 32. |
Usage Guidelines
This command does not delete static group memberships configured on interfaces.
Deleting IGMP entries on an interface does not prevent the interface from joining the involved groups again.
After IGMP group memberships are deleted, group members may fail to receive multicast data. Therefore, exercise caution when using this command.
Example
# Delete dynamic IGMP entries on all interfaces.
<HUAWEI> reset igmp group all
# Delete all dynamic IGMP entries on VLANIF100.
<HUAWEI> reset igmp group interface vlanif 100 all
# Delete the IGMP entries of group 225.0.0.1 on VLANIF100.
<HUAWEI> reset igmp group interface vlanif 100 225.0.0.1
# Delete IGMP entries of groups 225.1.1.0 to 225.1.1.255 on VLANIF100.
<HUAWEI> reset igmp group interface vlanif 100 225.1.1.0 mask 255.255.255.0
