问题 Open Shortest Path First(OSPF)is a(71)routing algorithm that(72)work done on the OSI IS-IS intradomain routing protocol. This routing, as compared to distance-vector routing, requires(73)processing power. The Dijkstra algorithm is used to calculate(74)OSPF routing table updates only take place when necessary,(75)at regular intervals.
