HP 5900 series Command Reference

Parameters
acl6-number: Specifies an IPv6 basic or advanced ACL by its number in the range of 2000 to 3999.
Receiver hosts can join only the IPv6 multicast groups that the ACL permits. If the specified ACL does not
exists or the specified ACL does not contain valid rules, receiver hosts cannot join IPv6 multicast groups.
version-number: Specifies an MLD version number, 1 or 2. By default, the configured group filter is
effective on both MLDv1 reports and MLDv2 reports.
Usage guidelines
In an IPv6 basic ACL, the source keyword matches the IPv6 multicast group address in MLD reports. In an
IPv6 advanced ACL, the source and destination keywords match the IPv6 multicast source address and
IPv6 multicast group address in MLD report, respectively. The multicast source address is considered to
be 0::0 for the following MLD reports:
• MLDv1 reports.
• MLDv2 IS_EX and MLDv2 TO-EX reports that do not carry IPv6 multicast source addresses.
If you specify the vpn-instance keyword in an ACL rule, the rule does not take effect. The other optional
parameters except the time-range keyword and the fragment keyword in the ACL rules are ignored.
This command controls the IPv6 multicast groups that the receiver hosts can join by filtering MLD
messages. This command does not take effect on a static member interface, because the static member
interface does not send MLD messages.
Examples
# Configure an IPv6 multicast group policy on VLAN-interface 100 so that hosts attached to the interface
can join only the IPv6 multicast group FF03::101.
