Hi folks,
OSPF Cost = Reference BW / Interface BW in bps
In the give example:
Ref BW= 1000Mbps = 1000,000,000 bps
OSPF cost of GE interface between R3 and R2 = 1000,000,000 / 1000,000,000 = 0.1 which is calculated as 1
Ethernet speed is 10Mbps(10,000,000 bps) between R1 and R2 { Cost= 1000,000,000/10,000,000 = 100}
Total cost of route learned by R3 = 1 + 100 = 101
but there is no option of 101, can anyone confirm my calculations please?
