  • 第6题:

    OSPF is a link-state routing protocol。It is designed to be run internal to a single ()system。Each OSPF router maintains an identical ()describing the autonomous system’s topology。From this database,a routing table is calculated by constructing a shortest-path ()。OSPF recalculates routes quickly in the face of topological changes,utilizing a minimum of routing () traffic。OSPF provides support for equal-cost multipath。An area routing capability is provided,enabling an additional level of routing protection and a reduction in routing protocol (75)。

    A.flow
    B.state
    C.traffiC.
    D.stream

    答案:C
    解析:
    OSPF是一种链路状态路由协议。该协议被设计成运行在单一的自治系统内部。每一个OFPF路由器都保持了同样的数据库,该数据库可以描述自治系统的拓扑图。通过该数据库,可以搭建的最短路径树以此计算路由表。OSPF在拓扑发生变化时,利用最小路由组播流量的快速重新计算路由。OSPF支持多条等价路径。OSPF提供区域路由的能力,在路由协议流量中赋予一个额外的路由保护和路由剪截能力。
