1、OSPF多区域配置实训名称】配置OSP F多区域。实训目的】配置OSP F多区域，理解OSP F层次型网络的特点。背景描述】本实训拓扑图中有3台路由器，路由器在区域0和区域1中，路由器B在区域0和区域30,路 由器C在区域30。【需求分析】需要基于本拓扑图实现OSP F多区域的配置，并理解OSP F实现层次型网络的优点。实训拓扑】实训的拓扑图，如图11-1所示。172.24.1.124a m.iiaj.ac24 72.iaj.0T24 OSPFOSPF Atm压阳比苗843诂4、1狛.11良|19-2.1 SgJ.I.J*OSPF Area 3D图11-1实训设备】路由器 3台预备知识】路由器
