CCNA WANs 3-3: Routing Table

📊 Administrative Distance & Metric: Administrative distance ranks routing protocols based on their reliability, with lower values indicating higher preference. Meanwhile, metrics like OSPF's cost or RIP's hop count measure the efficiency of specific routes, aiding routers in choosing the optimal path.

🔄 Choosing the Right Route: When faced with multiple routes to the same destination, routers rely on administrative distance and metric to make informed decisions. By prioritizing lower administrative distances and more favorable metrics, routers select the best route for forwarding packets.

📉 Longest Match Principle: But what if there are multiple matches in the routing table? Fear not! The longest match principle comes to the rescue, ensuring that routers prioritize routes with the most specific (longest) matches, guaranteeing accurate packet forwarding.

❌ No Matching Route?: In the rare event that there's no matching route in the routing table, packets meet their end – they're dropped. Without a suitable route to guide them, these lost packets vanish into the digital abyss.

💡 Key Takeaways: Administrative distance, metric, and the longest match principle are the guiding lights in the intricate world of routing tables. From route installation to packet forwarding, understanding these principles is essential for network administrators.

Good Morning....without the binary conversion how do i tell the longest match from the routing table? Is it simply The AD divided by the metric? OR the route with the highest CIDR notation?
