By default, what is the OSPF cost for any link with a bandwidth of 100 Mb/s or greater?

  • 100000000
  • 10000
  • 1
  • 100

Explanation: OSPF uses the formula: Cost = 100,000,000 / bandwidth. Because OSPF will only use integers as cost, any bandwidth of 100 Mb/s or greater will all equal a cost of 1.
