County planners ask why every leaf should connect to every spine in the municipal Clos. What is the primary architectural intent of that full leaf-to-spine wiring?
Select an answer to reveal the explanation.
Short Explanation
Picture every leaf as a city avenue and every spine as a freeway interchange—full mesh to the spines means cars always have equal on-ramps. That is how Clos keeps ECMP fair and bandwidth predictable. Skipping spines is how you invent weird bottlenecks.
Full Explanation
Full leaf-to-spine connectivity is the Clos pattern that enables uniform ECMP and non-blocking scale-out between any pair of leaves. Partial wiring creates uneven path sets and capacity hot spots. Spanning Tree and single-spine choke points contradict IP-fabric multipath design. Underlay advertisement of infrastructure prefixes remains required regardless of wiring completeness.
