To enable MLD snooping proxying in a VLAN:
Step Command
Remarks
1.
Enter system view.

2.
Enter VLAN view.
vlan vlan-id
N/A
3.
Enable MLD snooping
proxying in the VLAN.
mld-snooping proxying enable
Disabled by default
Configuring a source IPv6 address for the MLD messages sent
by the proxy
You can set the source IPv6 addresses in the MLD reports and done messages that the MLD snooping
proxy sends on behalf of its attached hosts.
To configure the source IPv6 addresses for the MLD messages in a VLAN:
Step Command
Remarks

3.
Configure a source IPv6
address for the MLD reports
that the proxy sends.
mld-snooping report source-ip
{ ipv6-address | current-interface }
The default is
FE80::02FF:FFFF:FE00:0001.
4.
Configure a source IPv6
address for the MLD done
messages that the proxy
sends.
mld-snooping done source-ip
{ ipv6-address | current-interface }
The default is
FE80::02FF:FFFF:FE00:0001.
Configuring an MLD snooping policy
Before you configure an MLD snooping policy, complete the following tasks:
•
Enable MLD snooping in the VLAN
•
Determine the IPv6 ACL rule for IPv6 multicast group filtering
•
Determine the maximum number of IPv6 multicast groups that a port can join
•
Determine the 802.1p precedence for MLD messages
Configuring an IPv6 multicast group filter
On an MLD snooping–enabled access controller, the configuration of an IPv6 multicast group filter
allows the service provider to define limits of multicast programs available to different users.
In an actual application, when a user requests a multicast program, the user's host initiates an MLD
report. After receiving this report message, the access controller checks the report against the configured
ACL rule. If the port on which the report was received can join this IPv6 multicast group, the access
controller adds an entry for this port in the MLD snooping forwarding table. Otherwise the access
controller drops this report message. Any IPv6 multicast data that fails the ACL check is not sent to this
port. In this way, the service provider can control the VOD programs provided for multicast users.
