Abstract: 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.
Keywords: multi area; open shortest path first protocol; link state advertisement; Packet Tracer
