EIGRP Feasible Condition — The Secret Behind Loop-Free Routing Ever wondered how EIGRP ensures fast convergence and loop-free backups? It’s all about the Feasibility Condition (FC) — where a backup route becomes a Feasible Successor only if its Reported Distance (RD) is less than the Feasible Distance (FD) of the successor route. 🔍 Mastering this concept helps you ace CCNA / CCNP and real-world network troubleshooting. 👉 Follow @guinettechnologies for daily insights on Networking | SD-WAN | Cy
