3. Configure an IPv6 multicast
group filter.
mld group-policy acl6-number
[ version-number ]
By default, no IPv6 group filter is
configured on the interface. Hosts
on the current interface can join
any multicast group.
NOTE:
If you configure the interface as a static member interface for an IPv6 multicast group or an IPv6 multicas
t
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:
