12、or第一章VLAN 技术附录一、复习答案1. 在网络中使用 VLAN 技术可以带来哪些好处？答：通过在网络中使用 VLAN 技术，可以减小广播域范围，从而减少广播流量，并且还能提供一定的故障隔离。2. VLAN ID 的编号范围是多少？答： VLAN ID 表示的范围是 04095 ，但是用户在设备上可以配置的 VLAN 范围是14094 。3. 当要跨交换机实现VLAN 内的通信时，应如何实现？Trunk 。答：跨交换机实现同VLAN 之间的通信时，交换机之间的级联接口应设置为4. 在穿过 Trunk 和 Access 接口时， VLAN 中的数据帧是如何被处理的？答：在穿过 Trunk 前
13、，除 Native VLAN 外的所有的 VLAN 数据帧都需要打上 802.1q 标签，穿过 Trunk 时标签保留。在穿过 Access 接口发出数据前，VLAN 数据中的 802.1q 标签会被剥除。5. 实现 VLAN 间通信有哪些方式？答：实现VLAN 间通信有三种方式：路由接口、SVI 接口和单臂路由。6. 通过 SVI 如何实现 VLAN 间通信？答：通过SVI 方式实现 VLAN 间路由，需要在三层交换机上为VLAN 的SVI 接口配置IP 地址，并且此地址作为本VLAN 中主机的默认网关，主机在发送数据到其他网段时，将数据发送给网关即三层交换机，再利用三层交换机的路由功能实现
14、路由。7. 通过单臂路由方式如何实现 VLAN 间通信？答：需要在路由器接口上创建以太网子接口，并将子接口封装802.1q 划分到各 VLAN 中，最后为子接口配置 IP 地址作为本 VLAN 主机的默认网关。8. 相比单臂路由方式，通过SVI 方式实现 VLAN 间通信有哪些优点？答：通过三层交换机的SVI 方式实现 VLAN 间路由，由于使用SVI 逻辑端口所以不受物理端口密度的限制，并且不会造成网络瓶颈，实施起来更加灵活方便。9. Private VLAN 中的属于同一 VLAN 的隔离端口是否可以通信？答：不能。10. Super VLAN的不同 Sub VLAN的端口是否可以实现二层
15、通信？答：不能第二章生成树协议 附录一、复习答案名师归纳总结 1、相对于 STP ，RSTP 中增加了哪些端口角色？ements to adhee to three principles: first, under the ex isting policy provisions approved for public servants duty consumption standards, calibration, is not contrary to policy.

36、商便可进入转发状态。在共享式链路中，则只能经过监听状态和学习状态才能进入转发状态。5、在 RSTP 中，当拓扑发生变化时，交换机是如何传递拓扑变更到整个网络的？答：在 RSTP 中，发现拓扑变化的交换机直接向网络中泛洪 TC BPDU 报文。6、如何将一个端口配置为 RSTP 边缘端口？答：使用接口命令 spanning-tree portfast。7、运行 STP 和RSTP 的网络会存在什么样的问题？答： STP 和RSTP 均没在网络中考虑VLAN 的环境，因此在网络中进行生成树运算并阻断链路时，可能会导致某些 VLAN 的通信受阻，并且会导致冗余链路空闲，造成带宽资源浪费。8、相比较
37、STP 与RSTP ，MSTP 最主要的区别是什么？答： MSTP 可以在网络中运行多个生成树。9、在运行 MSTP 的交换机中，默认情况下 VLAN 属于哪个实例？答：属于实力 0（instance 0 ）。10 、运行 MSTP 的网络中，具有哪些相同特性或配置的交换机会被视为在同一个区域中？答：配置相同的区域配置名称、修正号以及VLAN 与生成树实例的映射关系。11 、在运行 MSTP 的网络中，如何实现负载分担？答：当网络中有多个 VLAN 时，将不同的 VLAN 划分到不同的 instance 中，这样每个instance 会自己计算独立的生成树，再将不同instance 中的根交换
38、机通过优先级的配置设置为不同的交换机，从而使不同的 VLAN 可以通过不同的链路发送数据，实现数据的负载分担。第三章虚拟路由器冗余协议（一、复习答案 1、VRRP 运行过程中会经历哪三种状态？答： Initialize 、Master 和Backup 。VRRP ） 附录2、VRRP 报文的组播地址是多少？协议号是多少？答：组播地址为 224.0.0.18 ，IP 协议号为 112 。3、VRRP 是如何进行选举的？答：运行VRRP 的路由器通过发送和接收VRRP 通告报文来比较优先级，优先级大的将成为主路由器，其它路由器都为备份路由器。4、VRRP 使用几个定时器？各定时器的作用是什么？答：
39、 VRRP 使用两个时间定时器，通告间隔定时器和主路由器失效间隔定时器。通告间隔定时器用于定义路由器发送VRRP 通告报文的间隔，主路由器失效定时器用于定义备份路由器在认为主路由器失效前所等待的时间。5、什么是 IP地址拥有者？答：虚拟 IP 地址与接口 IP 地址相同的 VRRP 路由器被称为 IP 地址拥有者。6、VRRP 使用什么方法实现流量的负载均衡？名师归纳总结 答：通过将路由器加入到多个s a difficult problem that must be VRRP 组中，并且使路由器在不同的组中承担不同的角色 solved i n the reform pr oce ss.
