Figure 36 MLD snooping related ports
The following describes the ports involved in MLD snooping, as shown in
Router port—Layer 3 multicast device-side port. Layer 3 multicast devices include designated
•
routers and MLD queriers. In
Ten-GigabitEthernet 1/1/5 of Switch B are the router ports. A switch records 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 a Layer 2 interface.
Member port—Multicast receiver-side port. In
•
Ten-GigabitEthernet 1/1/7 of Switch A and Ten-GigabitEthernet 1/1/6 of Switch B are member
ports. A switch records 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.
NOTE:
When MLD snooping is enabled, all ports that receive IPv6 PIM hello messages or MLD general queries
with a source IP address other than 0::0 are considered dynamic router ports. For more information about
IPv6 PIM hello messages, see

Description
When a port receives an MLD general
query with the source address other
than 0::0 or IPv6 PIM hello message,
the switch starts or resets an aging
timer for the port. When the timer
expires, the dynamic router port ages
out.
