OSPF单区域配置-Cisco Packet Tracer v7.0思科网络模拟器实验练习

**        OSPF****是一种常用的动态路由协议，采用SPF算法计算最优路由。**

**        OSPF****的算法好、收敛快、支持大型且复杂的网络结构、不容易被有害路由信息影响。**

**        OSPF****可适应各种大规模网络，可支持区域划分，可基于带宽来选择最佳路由，无路由自环等优点。**

**OSPF****划分区域的好处是减少LSA的数量和屏蔽了网络变化波及的范围。**

**        OSPF****路由协议是一种典型的链路状态（Link-state）的路由协议，一般用于同一个路由域内。路由域是指一个自治系统（Autonomous System），即AS，它是指一组通过统一的路由政策或路由协议互相交换路由信息的网络。在这个AS中，所有的OSPF路由器都维护一个相同的描述这个AS结构的数据库，该数据库中存放的是路由域中相应链路的状态信息，OSPF路由器正是通过这个数据库计算出其OSPF路由表的。作为一种链路状态的路由协议，OSPF将链路状态广播数据包LSA（Link State Advertisement）传送给在某一区域内的所有路由器，这一点与距离矢量路由协议不同。运行距离矢量路由协议的路由器是将部分或全部的路由表传递给与其相邻的路由器。**
