coming from the router to be propagated through the network, as well as allowing multicast messages (IGMP) coming from the network to be propagated to the router.
A router port has the following behavior:
•All IGMP Report packets will be forwarded to the router port.
•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 the 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,
