Step
3.
Configure the interface as a
static member interface.

Configuring an IPv6 multicast group filter

To restrict the hosts on the network attached to an interface from joining certain IPv6 multicast groups,
you can specify an IPv6 ACL on the interface as a packet filter so that the interface maintains only the
IPv6 multicast groups that match the criteria.
To configure an IPv6 multicast group filter:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure an IPv6 multicast
group filter.
NOTE:
If you configure the interface as a static member interface for an IPv6 multicast group or an IPv6 multicast
source and group, this configuration is not effective for the IPv6 multicast group or the IPv6 multicast
source and group.

Adjusting MLD performance

Before adjusting MLD performance, complete the following tasks:
Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices can be
interoperable at the network layer.
Configure basic MLD functions.

Enabling MLD fast-leave processing

In some applications, such as ADSL dial-up networking, only one multicast receiver host is attached to an
interface of the MLD querier. To allow fast response to the MLD done messages of the host when it
switches frequently from one IPv6 multicast group to another, you can enable fast-leave processing on the
MLD querier.
With MLD fast-leave processing enabled, after receiving an MLD done message from a host, the MLD
querier sends a leave notification to the upstream immediately without first sending MLD
multicast-address-specific queries. This reduces leave latency and preserves the network bandwidth.
To enable MLD fast-leave processing:
Command
mld static-group
ipv6-group-address [ source
ipv6-source-address ]
Command
system-view
interface interface-type
interface-number
mld group-policy acl6-number
[ version-number ]
130
Remarks
By default, an interface is not a
static member of any IPv6 multicast
group or IPv6 multicast source and
group.
Remarks
N/A
N/A
By default, no IPv6 group filter is
configured on the interface. That is,
hosts on the current interface can
join any multicast group.
