OSPF Metric calculation

Just quick note cause i always forget this part , now how does OSPF calculate it's metric and what i mean by metric i mean when you issue the command (show ip route) what's this metric how did it get it ?

Cost  = (10 Mgb/s / BW ) 

Rack1SW2#sh ip route 150.1.6.0
Routing entry for 150.1.6.0/24
  Known via "ospf 1", distance 110, metric 63, type inter area
  Last update from 155.1.58.5 on Vlan58, 00:30:07 ago
  Routing Descriptor Blocks:
  * 155.1.58.5, from 150.1.5.5, 00:30:07 ago, via Vlan58
      Route metric is 63, traffic share count is 1

Now we need to see who advertise this route , OSPF as INE explains works as both distance vector and link state at the same way , distance vector in a fashion that it deduce its metric for inter-area routes based on the metric advertised by the ABR , then it caclulates it's cost of reaching the ABR itself

Rack1SW2#show ip ospf database summary 150.1.6.0

            OSPF Router with ID (150.1.8.8) (Process ID 1)

                Summary Net Link States (Area 3)

  Routing Bit Set on this LSA
  LS age: 1798
  Options: (No TOS-capability, DC, Upward)
  LS Type: Summary Links(Network)
  Link State ID: 150.1.6.0 (summary Network Number)
  Advertising Router: 150.1.5.5 <<<<<< ABR router
  LS Seq Number: 80000003
  Checksum: 0x6B52
  Length: 28
  Network Mask: /24
        TOS: 0  Metric: 62<<<<<<< Metric advertised by ABR


Rack1SW2#show ip ospf int Vlan58 | i Cost
  Process ID 1, Router ID 150.1.8.8, Network Type BROADCAST, Cost: 1

Therefore we deduce total cost to be = 62 + 1 = 63
