Interfaces Attached to a Multicast Router
Multicast routers use the information obtained from IGMP Query, along with a
multicast routing protocol such as DVMRP, to support IP multicasting across the
Internet. These routers may be dynamically discovered by the switch or statically
assigned to an interface on the switch.
