What is the reason for a network engineer to alter the default reference bandwidth parameter when configuring OSPF?

  • to more accurately reflect the cost of links greater than 100 Mb/s
  • to increase the speed of the link
  • to force that specific link to be used in the destination route
  • to enable the link for OSPF routing
    Answers Explanation & Hints:

    By default, Fast Ethernet, Gigabit, and 10 Gigabit Ethernet interfaces all have a cost of 1. Altering the default reference bandwidth alters the cost calculation, allowing each speed to be more accurately reflected in the cost.
