003 DR BDR ELections

In this video, we explore DR & BDR (Designated Router & Backup Designated Router) Elections in OSPF (Open Shortest Path First), explained by Sikandar Shaik. DR/BDR elections play a crucial role in multi-access networks by optimizing OSPF communication and reducing overhead.

🔹 What You’ll Learn in This Video:
✅ What is a Designated Router (DR) and Backup Designated Router (BDR)?
✅ The importance of DR/BDR in OSPF networks
✅ How the DR/BDR election process works
✅ The role of Router IDs and priorities in elections
✅ How to manually influence the DR/BDR selection
✅ Real-world examples and practical configurations

When multiple OSPF routers exist in a broadcast multi-access network, such as Ethernet, the election of a DR and BDR ensures that OSPF updates are efficiently managed, preventing unnecessary flooding of LSAs. Understanding how these elections take place and how to control them is crucial for network engineers and Cisco certification candidates.

This video is ideal for those preparing for Cisco CCNA, CCNP, or anyone looking to improve their OSPF troubleshooting and configuration skills. Sikandar Shaik provides a clear and detailed explanation to help you master DR & BDR elections in OSPF.

What if we have two different priorities on different interface on Single OSPF Router??
