Routers perform the decision process that selects what path a packet takes. These ( ) layer devices participate it the collection and distribution of network-layer information, and perform Layer 3 switching based on the contents of the network layer ( ) of each packet. You can connect the routers directly by point-to-point ( ) or local-area networks, or you can connect them by LAN or WAN switches. These Layer 2 switches unfortunately do not have the capability to hold Layer 3 ( ) information or to select the path taken by a packet through analysis of its Layer 3 destination address. Thus, Layer 2 switches be involved in the Layer 3 packet ( ) decision process.A.headerB.connectionC.protocolD.data

C.protocol
D.data
答案
A
解析
路由器完成决策过程,选择分组要走的通路。这些网络层设备加入分发网络层信息的集合,基于每一个分组网络层头部的内容完成第三层交换功能。你可以直接通过点对点链路或局域网连接路由器,也可以用 LAN 或 WAN 交换机连接它们。但是这些第二层交换机不具有保存第三层路由信息的能力,也不能通过分析第三层目标地址选择分组要经过的通路。于是,第二层交换机不会涉入第三层分组转发的决策过程。
