Default command level
2: System level
Parameters
acl6-number: Specifies a basic or advanced IPv6 ACL in the range of 2000 to 3999. A host can join only
the IPv6 multicast groups that match the permit statement in the ACL. The source address or address
range specified in the advanced IPv6 ACL rule is the IPv6 multicast source address or addresses specified
in MLDv2 reports, rather than the source address in the IPv6 packets. The system assumes that an MLDv1
report or an MLDv2 IS_EX or TO_EX report that does not carry an IPv6 multicast source address carries
an IPv6 multicast source address of 0::0.
version-number: Specifies an MLD version number, 1 or 2. If you do not specify an MLD version, the
configured group filter is effective on both MLDv1 reports and MLDv2 reports.
Usage guidelines
For a device that supports both MLD snooping and MLD, you can also use the group-policy
(MLD-Snooping view) command to control the IPv6 multicast groups that hosts in a VLAN can join,
achieving the same result as mld group-policy. If you have configured a multicast group filter on a VLAN
interface to control the multicast groups that the hosts on the interface can join, HP recommends you to
configure the same multicast group filter in the corresponding VLAN.
Examples
# Configure an IPv6 ACL so that hosts on Ethernet 1/1 can join the IPv6 multicast group FF03::101 only.
