What is the Cisco metric for OSPF?

Cisco uses a metric for OSPF that is calculated as 108 / bandwidth. This cost value is of 100 Mb/s (reference bandwidth) divided by the interface bandwidth. Delay, bandwidth, reliability, and load are used as a composite metric with EIGRP. K metrics are used to weight the calculation of the composite metric used with EIGRP. Bandwidth is used by OSPF, but only when used with the formula of 108 / bandwidth.
