The operations team debates installing heavy, complex FBF policies on every leaf versus steering at a smaller set of centralized choke points. What placement tradeoff should drive the decision?
Select an answer to reveal the explanation.
Short Explanation
Spray the same complicated detour on every neighborhood street and you maintain it everywhere; put one gate downtown and everyone depends on that gate. Leaf-wide FBF buys local enforcement at the cost of sprawl; centralized steer is simpler to run but a bigger single funnel.
Full Explanation
FBF placement is an operational design choice. Applying rich filters on every leaf distributes enforcement close to endpoints but multiplies configuration surface and consistency risk. Centralized steering reduces policy sprawl yet creates concentrated dependency and potential bottlenecks. Spines are not the only valid attachment points, and EVPN tags do not eliminate the need for FBF classification when FBF is the chosen steering tool.
