In Cisco IOS Release 10.3 and later, by default OSPF will calculate the OSPF
metric for an interface according to the bandwidth of the interface. For
example, a 64K link will get a metric of 1562, while a T1 link will have a
metric of 64.
The OSPF metric is calculated as ref-bw divided by bandwidth, with ref-bw
equal to 108 by default, and bandwidth determined by the bandwidth command.
The calculation gives FDDI a metric of 1.
If you have multiple links with high bandwidth (such as FDDI or ATM), you
might want to use a larger number to differentiate the cost on those links.
