摘　　要：针对多区域OSPF异形划分造成的网络通信故障问题,通过分析OSPF异形区域的存在形式,引入虚连接的工作机制,对OSPF骨干区域进行虚拟扩展和拉伸,形成一个Transit区域,并在其中建立逻辑通道,利用Router-ID实现Transit区域两台ABR之间的点对点通信。实验仿真结果显示,建立虚连接后的OSPF异形区域网络通信稳定可靠,证明了该方法的有效性。To avoid the network communication failure caused by the heteromorphic division of multi-area OSPF,the working mechanism of the virtual link is introduced to virtually expand and stretch the OSPF backbone area to form a transit area based on the analysis of the existence form of these areas.A logical channel is established in the transit area and point-to-point communication is realized by Router-ID between two ABRs.The simulation experiment results show that the network communication of OSPF heteromorphic area is stable and reliable after establishing the virtual link,which proves the effectiveness of this method.
