CCNA Exam Prep 35, OSPF DR and BDR Election

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.
