OSPF DR/BDR Election Explained | Multi-Access Network

In this week's video, we continue from our basic OSPF setup and dive into the mechanics of Designated Router (DR) and Backup Designated Router (BDR) elections in multi-access networks like Ethernet. Learn how OSPF determines which routers take charge, why DR/BDR roles matter, and how network topology influences the election process. Perfect for CCNA/CCNP prep or anyone looking to solidify their routing fundamentals. Topics Covered: • What is a multi-access network? • DR/BDR election process in OSPF • Priority settings and router ID influence • Configuration examples Ling to configs:[GitHub](https://github.com/null0labs/OSPF-Video1/tree/main/Video2) 00:00 - Intro 00:26 - Presentation 08:15 - Lab Demo 32:44 - Outro 🛠️ Stuff I Use 🛠️ EVE-NG - multivendor network emulation software.
