    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The function of DR/BDR elections on OSPF broadcast networks (like Ethernet) to reduce adjacencies. - How OSPF uses multicast addresses 224.0.0.5 and 224.0.0.6 on broadcast networks. - Why OSPF point-to-point networks do not elect a Designated Router (DR) or Backup Designated Router (BDR). - Common exam traps like mismatched network types or timers preventing OSPF adjacency. - The DR election process: highest OSPF priority, then highest router ID as the tiebreaker.

  • CCNA Exam Prep 35, OSPF DR and BDR Election

    CCNA Exam Prep 35, OSPF DR and BDR Election
    Jun 16 2026
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The OSPF DR/BDR election only occurs on multi-access networks to reduce LSA flooding. - The router with the highest OSPF interface priority (0-255) wins the DR election; a priority of 0 makes a router ineligible. - The highest router ID is used as the tie-breaker if interface priorities are equal. - The election process is non-preemptive; a new router with a higher priority will not take over an already-elected DR. - DROTHERs form a FULL adjacency with the DR and BDR, but only a 2-WAY state with other DROTHERs.

  • CCNA Exam Prep 34, OSPF Neighbor Adjacency States

    CCNA Exam Prep 34, OSPF Neighbor Adjacency States
    Jun 15 2026
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. 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?"
