【问题2】 在一台安装Windows 2003操作系统的双协议栈主机的cmd窗口中,键入“netsh interface ipv6 show interface”可获得如图7-11所示的系统输出信息,请指出图7-11中“MTU”的含义。另外如想查看该主机IPv6路由表则需要输入什么命令

答案

参考答案:

解析:MTU:最大传输单位 显示IPv6路由衷命令:netsh interface ipv6 show routes这是一道要求读者掌握IPv6常用命令及其结果信息分析的实践操作题。本题的解答思路如下。 1)Windows 2003操作系统提供对IPv6的支持,依次单击“开始”、“控制面板”命令,然后双击“网络连接”图标,接着用鼠标右键单击任一本地连接,在弹出的菜单中单击[属性]命令。点击[安装]按钮,在“选择网络组件类型”对话框中,单击[协议],然后单击[添加]按钮。在“选择网络协议”对话框中,单击“Microsoft TCP/IP版本6”,然后单击[确定] 按钮,最后单击[关闭]按钮以保存对网络连接所做的更改。网卡中成功绑定IPv6协议的示意图见图7-19。

2)Windows 2003操作系统中netsh.exe工具提供IPv6配置信息。使用“netsh interface ipv6 show interface”命令可显示 IPv6接口的列表,其中包括接口索引、接口跃点数、最大传输单位(MTU)、状态和名称。其中,MTU是Maximum Transmission Unit的英文缩写,是指在网络上可以传输的最大的数据包,其大小取决于所涉及的网络。 3)Windows 2003操作系统中,使用“netsh interface ipv6 show routes”命令可显示IPv6路由表,以及相关路由是否已发布和路由类型等信息。使用“netsh interface ipv6 show address”命令可显示分配给每个接口的IPv6地址、地址的类型、重复地址检测(DAD)状态及生命期等信息。

One spring,when 1 was 1 0,during one of my father’s layoffs,I could tell my mother was unhappy.I decided to cheer her up by buying her a special Mother’s Day gift.

One day after school I rode my bike to the Agins,which,I learned years later,was known for its high-end fashions and style.I introduced myself to Sylvia Agins,telling her I was looking for a Mother’s Day present.

“Do you think she’d like a purse ?”she asked.“I think she might.”I told her.

She took out an Italian purse made of leather.She asked me what I thought,and I told her that my mom would like it.

“How much money do you have?’’she asked.

“Twelve dollars,”I said.

“You’re in luck,”she told me.“It’s only $11.You have a dollar left over for the card.” She wrapped the purse and thanked me for my business,and I rode off home with the package under my arm.

When my mother opened the gift the next Sunday morning,she asked in an accusing tone,“Where did you get this?”

“I bought it at the Agins.It cost me$1 1.’’I said.

My mother was shocked into silence.

It wasn’t until many years 1ater,when I learned that the purse was worth several hundred dollars,that I appreciated just how wonderful Sylvia Agins had been to me.I always felt regretful  that I never had a chance to properly thank her.

‘‘You know,my son,what really amazes me to this day,”my mother said.‘‘Letting you have the purse for just a few dollars was unbelievable enough.But the fact that she let you leave the store with a dollar for the card was a touch of kindness that 9 11 never forget.”
