Configuring an MLD snooping policy

Configuration prerequisites

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 switch, the configuration of an IPv6 multicast group filter enables 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 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 is not sent to this port. In this way, the service provider can control

the VOD programs provided for multicast users.

Configuring an IPv6 multicast group filter globally

Follow these steps to configure an IPv6 multicast group globally:

Configure an IPv6 multicast group
filter

group-policy acl6-number [ vlan
vlan-list ]

Required
By default, no IPv6 group filter is

globally configured. That is, the
hosts in a VLAN can join any valid

multicast group.

Configuring an IPv6 multicast group filter on a port or a group of ports

Follow these steps to configure an IPv6 multicast group filer on a port or a group of ports:
