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:

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

3. Configure the maximum number of
IPv6 multicast groups that the
interface can join.
mld group-limit limit
By default, the upper limit is
4096.
NOTE:
This configuration takes effect for dynamically joined IPv6 multicast groups but not the statically
configured multicast groups.
Adjusting MLD performance
NOTE:
In MLD view, the configuration is effective globally. In interface view, the configuration is effective on
only the current interface.
If the same function or parameter is configured in both MLD view and interface view, the confi
g
uration
performed in interface view is given priority, regardless of the configuration sequence.
Configuration prerequisites
Before adjusting MLD performance, complete the following tasks:
