Step 2. Enter interface view. Command interface interface-type interface-number 3. Configure the interface as a static member interface. mld static-group ipv6-group-address [ source ipv6-source-address ] Remarks N/A By default, an interface is not a static member of any IPv6 multicast group or IPv6 multicast source and group. 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 ACL. To configure an IPv6 multicast group filter: Step 1. Enter system view. 2. Enter interface view. Command system-view interface interface-type interface-number 3. Configure an IPv6 multicast group filter. mld group-policy acl6-number [ version-number ] Remarks N/A N/A 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 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. 133

N/A
3.
Configure the interface as a
static member interface.
mld static-group
ipv6-group-address
[

]
By default, an interface is not a
static member of any IPv6 multicast
group or IPv6 multicast source and
group.
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 ACL.
To configure an IPv6 multicast group filter:

N/A
3.
Configure an IPv6 multicast
group filter.
mld group-policy
acl6-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 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.
