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.
Follow these steps to configure an IPv6 multicast group filter:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view
interface interface-type
interface-number
—
Configure an IPv6 multicast
group filter mld group-policy acl6-number
[ version-number ]
Required
By default, no IPv6 multicast
group filter is configured on this
interface, namely hosts on the
current interface can join any
valid IPv6 multicast group.
Configuring the Maximum Number of IPv6 Multicast Groups on an Interface
You can configure the allowed maximum number of the IPv6 multicast groups on an interface to flexibly
control the number of IPv6 multicast groups the interface can join.
Follow these steps to configure the maximum number of IPv6 multicast groups an interface can join:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view
interface interface-type
interface-number
—
Configure the maximum number of
IPv6 multicast groups that can be
joined on the current interface
mld group-limit limit
Required
1024 by default
This configuration takes effect for dynamically joined IPv6 multicast groups but not the statically
configured multicast groups.
