The l2-multicast-bind vlan command binds user VLANs to a multicast VLAN on an interface.
The undo l2-multicast-bind vlan command restores the default setting.
By default, no user VLAN is bound to a multicast VLAN on an interface.
l2-multicast-bind vlan vlan-id1 [ to vlan-id2 ] mvlan mvlan-id
undo l2-multicast-bind vlan { vlan-id1 [ to vlan-id2 ] | all }
| Parameter | Description | Value |
|---|---|---|
| vlan vlan-id1 [ to vlan-id2 ] | Specifies the ID of a user VLAN. |
The value is an integer that ranges from 1 to 4094. |
| mvlan mvlan-id | Specifies the ID of a multicast VLAN. |
The value is an integer that ranges from 1 to 4094. |
| all | Unbinds all user VLANs from the multicast VLAN on an interface. | - |

Usage Scenario
A carrier provides the multicast service for multiple Internet service providers (ISPs), and each ISP is assigned a multicast VLAN to isolate multicast data and routes of different ISPs. Users connected to different user-side interfaces of the switch may order multicast services of different ISPs but belong to the same user VLAN. If multicast replication based on user VLANs is used in this case, users may receive multicast data they do not require. This affects the income of the ISPs.
To solve this problem, bind the user VLAN to multicast VLANs of the ISPs whose services are ordered on user-side interfaces. Then the user-side interfaces accept only the data from multicast VLANs of the specified ISPs.
Prerequisites
IGMP snooping has been enabled using the igmp-snooping enable (VLAN view) command on the multicast VLAN.
Precautions
Before running this command, run the vlan command to create the corresponding user VLAN and multicast VLAN. Otherwise, configuration of this command does not take effect.
On an interface, a user VLAN can be bound to only one multicast VLAN.
Currently, the binding of user VLANs to a multicast VLAN on an interface is only supported on IPv4 networks.
