摘要
链路状态路由协议OSPF是目前业内使用最为广泛的IGP,协议原理复杂。基于Packet Tracer进行多区域OSPF仿真实验设计,充分体现分层路由思想,结合链路状态数据库分析和路由分析,对比区域内部路由器和区域边界路由器LSDB和路由表项的异同,明确多区域关系,以及收敛后各区域LSDB的同步状。实验逻辑清晰,有助于学生在实际应用场景中灵活运用相关理论正确部署OSPF路由协议。
Link state routing protocol OSPF is the most widely used IGP in the industry at present,and the protocol principle is complex.The multi area OSPF simulation experiment is designed based on Packet Tracer,which fully reflects the idea of hierarchical routing.Combined with link state database analysis and routing analysis,the similarities and differences between LSDB and routing table items of regional internal router and regional boundary router are compared,and the multi area relationship and the synchronization of LSDB in each area after convergence are clarified.The experimental logic is clear,which is helpful for students to flexibly use relevant theories to correctly deploy OSPF routing protocol in practical application scenarios.
