How does EIGRP handle load balancing over unequal cost paths?
- Achieves load balancing by always selecting the path with the lowest reported distance.
- Employs a round-robin approach for load balancing over unequal cost paths.
- Supports load balancing only on paths with equal costs, and unequal-cost paths are ignored.
- Utilizes equal-cost load balancing by default, and unequal-cost load balancing can be achieved using the "variance" command.
EIGRP can perform equal-cost load balancing by default and allows unequal-cost load balancing through the use of the "variance" command.
