All routers exchange routing tables with each other iIn a multipoint network.<br>C. Packets are routed based upon the shortest path to the destination.<br>D. Paths are chosen depending on the cost efficiency factor.<br>E. Every router in an OSPF area is capable of representing the entire network topology.<br>F. Only the designated router in an OSPF area can represent the entire network topology.<br><br>答案：ACE<br><br>D错在哪里？？？<br>

cost.

OSPF不是以cost为度量来选择路由？

是以最短cost来选择。所以叫做ospf。

通过拓扑表来来计算最短路径
