Quick question after going back and re-watching the OSPF and EIGRP episodes in the CCNA Routing and Switching lineup. So to compare the two:
Reference bandwidth / actual bandwidth = COST
Reference bandwidth is 100 Mbps or 100,000,000 bits.
( Diffusing Update Algorithm - DUAL)
Reference bandwidth / actual bandwidth * 256 = (Feasible Distance?)
Reference bandwidth is 10 Mbps or 10,000,000
What wasn't clear in each episode was the metric used for "actual bandwidth" in each calculation/formula. In the OSPF episode it appeared that the "actual bandwidth" was measured in bits for the purposes of the calculation whereas in the DUAL algorithm the "actual bandwidth" was measured in Kilobits per second or Kbps.
So a T1 for example would be 1,544 if you were doing EIGRP and 1,544,000 if you were doing the OSPF calculation. Am I correct here?
One follow up question for the purpose of the exam.. The result of the OSPF calculation is called "Cost", but what is the result of the EIGRP calculation called? Feasible Distance?
