链路状态协议 传递最佳的路径信息给其它的路由器 LSA（link state advertisement)数据包 链路状态公告 SPF 运算 拓补结构数据 最佳路由信息 路由表 C A D B * Purpose: This figure introduces the link-state routing algorithm, the second of the classes of routing protocols, and outlines how it operates. Emphasize: In contrast with the analogy about the distance vector information being like individual road signs that show distance, link-state information is somewhat analogous to a road map with a “you are here” pointer showing the map reader’s current location. This larger perspective indicates the shortest path to the destination. Each router has its own map of the complete topology. Link-state routing is not covered further in this course. Refer students interested in more details to the ACRC course.
