Description
Set the reference bandwidth used in calculating the default interface cost. The cost is calculated using the following formula:
cost = ref-bandwidth/bandwidth
Options
reference-bandwidth—Reference bandwidth, in bits per second.
Range: 9600 through 4,000,000,000,000 bits
Default: 100 Mbps (100,000,000 bits)
The default behavior is to use the reference-bandwidth
value to calculate the cost of OSPF interfaces. You can override this
behavior for any OSPF interface by configuring a specific cost with
the metric statement.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
