Which unique EIGRP feature allows for faster Layer 3 convergence?

The correct answer is B. feasible successors. Feasible successors are pre-computed backup routes stored in EIGRP's topology table that are guaranteed to be loop-free (they satisfy the feasibility condition). When the primary route (the successor) fails, EIGRP can immediately promote a feasible successor to the routing…

Explanation

Feasible successors are pre-computed backup routes stored in EIGRP's topology table that are guaranteed to be loop-free (they satisfy the feasibility condition). When the primary route (the successor) fails, EIGRP can immediately promote a feasible successor to the routing table without running the DUAL algorithm or querying neighbors, resulting in near-instant convergence. This is EIGRP's most distinctive convergence advantage over other routing protocols.
