In addition to building and maintaining lists of multicast group memberships, the MLD
snooping switch also maintains a list of multicast routers. Multicast packets are forwarded on
ports to which multicast routers are connected. With MLD snooping, only one querier can be
active in the network. All other routers in the network are suppressed and are not detectable
by the switch. If a query is not received on an interface within a specified period, the interface
is removed from the list of interfaces to which multicast routers are attached. However, by
default, the multicast router expiration time is zero, that is, the multicast router does not
expire.
A statically configured router that is connected to an interface or VLAN on the switch is
automatically added to the list with learned multicast routers. The interface must be active or
must be both active and a member of the VLAN.
