IGMP queries (from the router port) will be flooded to all ports.
All UDP multicast packets will be forwarded to the router port. Because routers do not send IGMP reports or implement IGMP
snooping, a multicast router connected to the router port of a Layer 3 switch would not be able to receive UDP data streams unless
the UDP multicast packets were all forwarded to the router port.
A router port will be dynamically configured when IGMP query packets, RIPv2 multicast, DVMRP multicast or PIM-DM
multicast packets are detected flowing into a port.
