Basic MLD snooping concepts

MLD snooping related ports
As shown in
Switch B, and Host A and Host C are receiver hosts (namely, members of an IPv6 multicast group).
Figure 104 MLD snooping related ports
As shown in
Router port—Layer 3 multicast device-side port. Layer 3 multicast devices include designated
•
routers and MLD queriers. In the figure, Ethernet 1/1 of Switch A and Switch B are router ports. A
switch registers all its local router ports in the router port list.
Do not confuse the "router port" in MLD snooping with the "routed interface" commonly known as
the "Layer 3 interface." The router port in MLD snooping is the Layer 2 interface.
• Member port—Multicast receiver-side port. In the figure, Ethernet 1/2 and Ethernet 1/3 of Switch
A and Ethernet 1/2 of Switch B are member ports. A switch registers all its local member ports in
its MLD snooping forwarding table.
Unless otherwise specified, router ports and member ports in this document include both static and
dynamic router ports and member ports.
Dynamic router ports include ports that receive MLD general queries with the source address other than
0::0 and ports that receive IPv6 PIM hello messages. For more information about IPv6 PIM hello
messages, see "Configuring IPv6 PIM."
