答案D

解析 选项A中“162.105.151.0/24[110/2]via 162.105.254.14,GigabitEthemet4/2”中“GigabitEthernet4/2”错误,该位置应填入虚拟局域网号。选项B中“C 162.105.157.0/24 is directly connected,00:23:00,FastEthernet2/5、C 162.105.156.0/24 is directly(:onnected.00:23:00,FastEthemet2/7”处“FastEthemet2/5”和“Fast。Ethernet2/7”处错误,该位置应填入虚拟局域网号。选项C中“S 162.105.239.0/25[1/0]via GigabitEthernet4/2、S 162.105。125.128/26[1/0]via FastEthernet2/5”via关键字后面填具体的IP地址,而不是端口名称。故选择D选项。
