How to determine Metric cost

DerekAustin26

Network+ book says to determine the cost of a route metric you must divide the bandwidth in bps by 100,000,000

100Mb = 100,000,000 Correct?

Because the book shows a 100Mb path as a cost of 10
and a 1Gb path as a cost of 1

so OSPF will always choose the lowest cost

I thought 100Mb is 100 million. Megabits = Millions

Where am I going wrong?

If you are talking about OSPF cost. Then cost of 100mbps link would be 1
100 mbps = 100,000,000

cost=bandwidth/10power8
=100,000,000/100,000,000
= 1

So for a 1gbps cost would be 10
