Configuration
Prerequisites
Before configuring MLD Snooping port functions, complete the following task:
■ Enable MLD Snooping in the VLAN or enable MLD on the desired VLAN
interface
Before configuring MLD Snooping port functions, prepare the following data:
■ IPv6 multicast source addresses
■ Whether to enable the fast leave function or not
■ Whether to enable the MLD membership report suppression function
Configuring Static Ports If the host attached to a port is interested in the IPv6 multicast data addressed to a
particular IPv6 multicast group, you can configure this port to be a static member
port for that IPv6 multicast group.
In a network where the topology structure is unlikely to change, you can configure
one or more static router ports on a switch. When receiving IPv6 multicast data, it
forwards the data to both multicast group member ports and static router ports.
Follow these steps to configure static ports:
n
■ When you configure a port as a static IPv6 multicast group member port, the
port does not send an MLD report; when you remove a port as a static IPv6
multicast group member port, it does not send an MLD done message.
■ Static member ports and static router ports never age out. To delete such a
port, you need to use the corresponding command.
Configuring Simulated
Joining
Generally, a host running MLD responds to MLD queries from a multicast router. If
a host fails to respond due to some reasons, the multicast router will deem that no
