Assume that Host A needs to receive the information addressed to multicast group G 225.1.1.1. After
multicast source S 10.1 10.5.100/24 sends multicast packets to the multicast group G, an SPT is
established through traffic flooding. Switches on the SPT path (Switch A and Switch D) have their (S, G)
