David has configured the bandwidth of an OSPF interface with the “bandwidth 64” command. What is the calculated cost of the link?
  1. 1562
  2. 1
  3. 64
  4. 64000
Explanation
Answer - A - The calculated cost of the link is 1562.

Key Takeaway: Cisco IOS interprets the values for the bandwidth command in kbps, so the bandwidth is configured as 64 kbps. The metric for an OSPF defaults to 100,000,000/bandwidth. So 100,000,000 / 64000 = 1562.5.
