展示を参照してください。R1 が 172.16.1.1 宛てのパケットを受信した場合、どの IP アドレスにパケットを送信しますか?
正解:A
172.16.1.1 is not in the routing table this means it is a random address. But since a default static route of 0.0.0.0 has been configured and injected to OSPF with the next hope address of 192.168.14.4 through FastEthernet1/0, thus R1 will send the packet to 192.168.14.4.
