In this episode you will learn: - The seven OSPF neighbor states in order are Down, Init, 2-Way, ExStart, Exchange, Loading, and Full. - On broadcast networks, non-DR/BDR routers normally remain in the 2-Way state with each other and only reach Full with the DR and BDR. - A common cause for a failed OSPF adjacency is a mismatch in the Hello or Dead timers between neighboring routers. - The ExStart and Exchange states are where routers use Database Descriptor packets to summarize and compare their link-state databases. - A helpful mnemonic for the OSPF states is: "Do Interns 2-way Exchange Extra Large Fries?"
