Enabling Ipv6 Multicast Source Port Filtering - HP FlexNetwork 7500 Series Configuration Manual

Enabling IPv6 multicast source port filtering

This feature enables the switch to discard all IPv6 multicast data packets and to accept IPv6
multicast protocol packets. You can enable this feature on ports that connect to only IPv6 multicast
receivers.
You can enable multicast source port filtering for the specified ports in MLD-snooping view or for a
port in interface view. For a port, the configuration in interface view has the same priority as the
configuration in MLD-snooping view, and the most recent configuration takes effect.

Enabling dropping unknown IPv6 multicast data
This feature enables the switch to drop all unknown IPv6 multicast data. Unknown IPv6 multicast
data refers to IPv6 multicast data for which no forwarding entries exist in the MLD snooping
forwarding table.
Configuration restrictions and guidelines
When you enable dropping unknown IPv6 multicast data, follow these restrictions and guidelines:
•
You can enable this feature globally for all VLANs in MLD-snooping view or for a VLAN in VLAN
view.
•
The drop-unknown command in MLD-snooping view and the mld-snooping drop-unknown
command mutually exclusive. You cannot configure them on the same switch.
•
If you enable dropping unknown IPv6 and IPv4 multicast data, enable both of them globally or
for the same VLANs to ensure correct multicast forwarding. For more informational bout
enabling dropping unknown IPv4 multicast data, see
•
When dropping unknown IPv6 multicast data is enabled, the switch still forward unknown IPv6
multicast data to other router ports in the VLAN.
