Configuring The Source Ipv6 Addresses For The Mld Messages Sent By The Proxy; Configuring An Mld Snooping Policy; Configuring An Ipv6 Multicast Group Filter - HP 6125G Configuration Manual

Configuring the source IPv6 addresses for the MLD messages
sent by the proxy
You can set the source IPv6 addresses for the MLD reports and done messages that the MLD snooping
proxy sends on behalf of its attached hosts.
To configure the source IPv6 addresses for the MLD messages that the MLD snooping proxy sends in a
VLAN:
Step
1. Enter system view.
2. Enter VLAN view.
3. Configure a source IPv6
address for the MLD
reports that the proxy
sends.
4. Configure a source IPv6
address for the MLD
done messages that the
proxy sends.

Configuring an MLD snooping policy

Before you configure an MLD snooping policy, complete the following tasks:
Enable MLD snooping in the VLAN.
•
• Determine the IPv6 ACL rule for IPv6 multicast group filtering.
Determine the maximum number of IPv6 multicast groups that a port can join.
•
Determine the 802.1p precedence for MLD messages.
•

Configuring an IPv6 multicast group filter

On an MLD snooping–enabled switch, you can configure an IPv6 multicast group filter to limit multicast
programs available to users.
In an application, when a user requests a multicast program, the user's host initiates an MLD report. After
receiving this report message, the switch resolves the IPv6 multicast group address in the report and looks
up the ACL. If a match is found to permit the port that received the report to join the IPv6 multicast group,
the switch creates an MLD snooping forwarding entry for the IPv6 multicast group and adds the port to
the forwarding entry. Otherwise, the switch drops this report message, in which case, the IPv6 multicast
data for the IPv6 multicast group is not sent to this port, and the user cannot retrieve the program.
When you configure a multicast group filter in an IPv6 multicast VLAN, be sure to configure the filter in
the sub-VLANs of the IPv6 multicast VLAN. Otherwise, the configuration does not take effect.
In MLDv2, when a host is enabled to join multiple multicast groups, the multicast group filter cannot
correctly filter multicast groups because the host that runs MLDv2 sends multiple multicast groups that it
wants to join in one membership report.
