Configuring an OSPF Cost for an Interface
You can configure an OSPF cost for an interface with one of the following two methods:
z Configure the cost value in interface view.
z Configure a bandwidth reference value for the interface, and OSPF computes the cost
automatically based on the bandwidth reference value: Interface OSPF cost= Bandwidth
reference value/Interface bandwidth. If the calculated cost is greater than 65535, the value of
65535 is used; if the calculated cost is less than 1, the value of 1 is used.
If no cost is configured for an interface, OSPF computes the interface cost automatically.
Follow these steps to configure an OSPF cost for an interface:

Optional
By default, an interface computes its cost
according to the bandwidth.
The cost value defaults to 0 on loopback
interfaces.
