The mld ip-source-policy command enables filtering of Multicast Listener Report/Done messages based on source addresses.
The undo mld ip-source-policy command disables filtering of MLD messages based on source addresses.
By default, a multicast device does not filter MLD messages based on source addresses.
| Parameter | Description | Value |
|---|---|---|
| basic-acl6-number | Specifies the number of a basic ACL6, which defines the range of source addresses. | The value is an integer that ranges from 2000 to 2999. |
GE interface view, XGE interface view, MultiGE interface view, 25GE interface view, 40GE interface view, 100GE interface view, Eth-Trunk interface view, VLANIF interface view, loopback interface view
Usage Scenario
MLD runs on receiver hosts and their directly connected multicast devices. A multicast device processes all received Multicast Listener Report/Done messages. For security purposes, you can configure the multicast device to filter Multicast Listener Report/Done messages received on an interface.
Prerequisites
Layer 3 IPv6 multicast has been enabled using the multicast ipv6 routing-enable command in the system view.
Precautions
For a numbered ACL, the mld ip-source-policy command works with the acl ipv6 command. You can configure the source address of MLD messages by specifying the source parameter in the rule command in the basic ACL view.
