Unlock the secrets of OSPF cost and reference bandwidth! 🚀

In this video, I explain how OSPF calculates interface costs, why the reference bandwidth matters, and how you can adjust it for modern high-speed networks. You’ll learn:

How OSPF determines path cost
Why all high-speed links default to cost 1
How to modify reference bandwidth consistently across routers
How to adjust link bandwidth and manually set OSPF cost

Perfect for CCNA, CCNP, and network engineers looking to master OSPF metrics!
