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 set an IPv6 ACL rule on the interface so that the interface maintains only the IPv6 multicast
groups matching the criteria.
To configure an IPv6 multicast group filter:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
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. That is,
hosts on the current interface can
join any valid multicast group.

interface can join

2. Enter interface view.
interface interface-type

N/A
3. Configure the maximum number of
IPv6 multicast groups that the
interface can join.
mld group-limit limit
The default is 4096.
This configuration only limits the
number of IPv6 multicast groups
that the interface dynamically joins.
Adjusting MLD performance
For the configuration tasks in this section, the following rules apply:
• The configurations made in MLD view are effective on all interfaces. The configurations in interface
view are effective only on the current interface.
• A configuration made in interface view always has priority over the same configuration in MLD view,
regardless of the configuration sequence.
Configuration prerequisites
Before adjusting MLD performance, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain can be interoperable at the network layer.
• Configure basic MLD functions.
