response, Host A creates an ARP entry, in which the destination IP address is the IP address of
Host D (192.168.1.30/16), and the MAC address is that of VLAN-interface 3. The following packets
sent from Host A to Host D will all be sent to VLAN-interface 3 of the switch, and then the switch
forwards the packets in Layer 3 to Host D, so as to realize the Layer 3 connectivity between Host A
and Host D.
