CCNAv7 - Enterprise Networking, Security, & Automation (ESNA) - Packet Tracer 2.3.11 (OSPF DR & BDR)

In this comprehensive and exhaustive techtorial on Packet Tracer activity 2.3.11 (Determine the DR & BDR) we take a deep dive into the the new Cisco Networking Academy CCNAv7 Enterprise Networking, Security, and Automation (ENSA) course curriculum! In this techtorial you will learn why OSPF needs to have a DR & BDR on broadcast/multi-access networks - and why you don't need one on point-to-point network types, which multicast addresses are used for communication with the DR, BDR, and DROTHERS, how to manipulate and influence the election of the DR & BDR, how to configure the 'ip ospf priority' command, why the DR/BDR election process is not preemptive, how to debug OSPF adjacency events, and how to validate and verify your DR and BDR configuration and status. We also go over the John T. Moy OSPF RFC, RFC 2328, and I introduce you to the two (2) legendary texts on the OSPF routing protocol - one by the creator, John T. Moy, and the other by routing legend, Jeff Doyle. Both books are "must haves" for any serious/professional network engineer who is working with OSPF. This techtorial/Packet Tracer activity is all done running Packet Tracer version 7.3.0 which was just released this week and is the MINIMUM version you can use for any of the new CCNAv7 curriculum activities! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time!
