Configuring an IPv6 multicast group filter on a port or a group of ports
Follow these steps to configure an IPv6 multicast group filer on a port or a group
of ports:
Configuring IPv6
Multicast Source Port
Filtering
With the IPv6 multicast source port filtering feature enabled on a port, the port
can be connected with IPv6 multicast receivers only rather than with multicast
sources, because the port will block all IPv6 multicast data packets while it permits
multicast protocol packets to pass.
If this feature is disabled on a port, the port can be connected with both multicast
sources and IPv6 multicast receivers.
Configuring IPv6 multicast source port filtering globally
