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 sent by the MLD
snooping proxy on behalf of its attached hosts.
Follow these steps to configure the source IPv6 addresses for the MLD messages sent by the MLD
snooping proxy on behalf of its attached hosts in a VLAN:

Configure a source
IPv6 address for the
MLD reports sent by
the proxy
mld-snooping report source-ip
{ ipv6-address |
current-interface }
Required
The default is
FE80::02FF:FFFF:FE00:0001.
Configure a source
IPv6 address for the

The default is
FE80::02FF:FFFF:FE00:0001.
Configuring an MLD Snooping Policy
Configuration Prerequisites
Before configuring an MLD snooping policy, complete the following tasks:
z
Enable MLD snooping in the VLAN
Before configuring an MLD snooping policy, prepare the following data:
z
IPv6 ACL rule for IPv6 multicast group filtering
z
The maximum number of IPv6 multicast groups that can pass the ports
z
802.1p precedence for MLD messages
Configuring an IPv6 Multicast Group Filter
On a MLD snooping–enabled switch, 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. Upon receiving this report message, the switch checks the report against the configured ACL
rule. If the port on which the report was received can join this IPv6 multicast group, the switch adds an
entry for this port in the MLD snooping forwarding table; otherwise the switch drops this report message.
Any IPv6 multicast data that fails the ACL check will not be sent to this port. In this way, the service
provider can control the VOD programs provided for multicast users.
