• Chose A4

  The answer seems A, but should be written far more clearly: "Configure feasible distance of successor route(best route) greater than the reported distance of the feasible successor(backup route). Explanation: The backup route is only passing feasibility condition if: Feasible distance of a successor route(best route) is LESS than the advertised distance of the successor route (backup route)

• Chose A4

  We have to achieve the feasibility condition in order to be able to have a feasible successor for the same path. OFC other parameters might needed (variance etc) but this is the first step. The Advertised Distance (AD) of the Feasible Successor (FS) must be lower than the Feasible Distance (FD) of the Successor. https://notes.networklessons.com/eigrp-feasibility-condition

  Tricky answers since these all say 'greater than'. Feasible successor's (secondary route) RD must be less than successor's (primary route) FD, so definitely not B or C. So answer A FD > RD is the only suitable answer
