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.

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