Enabling IPv6 multicast source port filtering
About IPv6 multicast source port filtering
This feature enables the Layer 2 device 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.
The configuration made in MLD-snooping view has the same priority over the interface-specific configuration.
Restrictions and guidelines
When IPv6 multicast source port filtering is enabled, the device automatically enables IPv4 multicast source port filtering.
The configuration made in MLD-snooping view has the same priority as the interface-specific configuration, and the most recent configuration takes effect.
