Parameter

acl6-number: Number of a basic or advanced IPv6 ACL, in the range of 2000 to
3999.

version-number: MLD version number, 1 or 2. If you do not specify an MLD
version, the configured group filter will apply to MLD reports of both version 1 and
version 2.

Description

Use the mld group-policy command to configure an IPv6 multicast group filter
on the current interface to limit access to the IPv6 multicast group.

Use the undo mld group-policy command to remove the configured IPv6
multicast group filter.

By default, no IPv6 multicast group filter is configured by default, that is, a host
can join any IPv6 multicast group.

When you use an advanced IPv6 ACL as a filter, the source address in the IPv6 ACL
is the multicast source address specified in the MLDv2 report message, instead of
the source address in the IPv6 message.

Example

# Configure an IPv6 ACL so that hosts on the subnet attached to Ethernet 1/0 can
join the IPv6 multicast group FF03::101 only.
