Configuring an MLD Snooping Policy

Configuration Prerequisites

Before configuring an MLD Snooping policy, complete the following tasks:
Enable MLD Snooping in the VLAN
Before configuring an MLD Snooping policy, prepare the following data:
IPv6 ACL rule for IPv6 multicast group filtering
The maximum number of IPv6 multicast groups that can pass the ports

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.
Configuring an IPv6 multicast group filter globally
Follow these steps to configure an IPv6 multicast group globally:
To do...
Enter system view
Enter MLD Snooping view
Configure an IPv6 multicast
group filter
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:
To do...
Enter system view
Enter Ethernet port/Layer 2
aggregate port view or port
group view
Use the command...
system-view
mld-snooping
group-policy acl6-number
[ vlan vlan-list ]
Use the command...
system-view
interface interface-type
interface-number
port-group manual
port-group-name
1-14

Required
By default, no group filter is globally
configured, that is, hosts in VLANs
can join any valid IPv6 multicast
group.
