9. Routing Protocol Metrics

Learn how routing protocol metrics work and how each protocol uses them to select the best path to a destination — a critical concept for the CCNA exam and for understanding how dynamic routing decisions are made! In this video, you'll learn: - What a routing metric is and why routing protocols need it - How different routing protocols use different metrics to measure path quality - How RIP uses hop count as its metric and why that leads to suboptimal routing - How OSPF uses cost based on interface bandwidth as its metric - How EIGRP uses a composite metric combining bandwidth and delay by default - How a lower metric always wins when comparing routes from the same protocol - What happens when two routes have equal metrics — equal-cost load balancing - How metrics differ from administrative distance and why both matter - How to view metric values in the routing table and topology table on Cisco routers Metrics are how routing protocols determine which path is best — and each protocol measures best differently. This video gives you a clear understanding of how metrics work across the most important routing protocols so you can predict routing behavior and troubleshoot path selection issues with confidence. @systemengineer7131 @CCNA
