Two EIGRP paths to 10.10.10.0 have feasible distances 3072 and 6144. What change enables EIGRP to load-balance across both paths?

EIGRP uses variance to allow unequal-cost load balancing. The variance command multiplies the feasible successor's feasible distance (FD) by a configured value. If the result is greater than or equal to the successor's FD, the feasible successor becomes a load-balancing path. In this case, the successor's FD is 3072. The feasible successor's FD is 6144. To include the feasible successor, we need 3072 variance = 6144. A variance of 2 satisfies this (3072 2 = 6144). Changing the maximum paths to 2 only allows for equal-cost load balancing. Changing the configuration so both have the same feasible distance is not practical or possible without altering the network topology. Changing IP addresses is irrelevant to EIGRP path selection.
