Item Description
Syntax reference-bandwidth reference-bandwidth
no reference-bandwidth
Context configure>service>vprn>ospf
Description This command configures the reference bandwidth in kilobits per second (Kbps) that provides
the reference for the default costing of interfaces based on their underlying link speed.
The default interface cost is calculated as follows:
cost = reference-bandwidth + bandwidth
The default reference-bandwidth is 100,000,000 Kbps or 100 Gbps, so the default auto-cost
metrics for various link speeds are as as follows:
• 10 Mbs link default cost of 10000
• 100 Mbs link default cost of 1000
• 1 Gbps link default cost of 100
• 10 Gbps link default cost of 10
The reference-bandwidth command assigns a default cost to the interface based on the
interface speed. To override this default cost on a particular interface, use the metric metric
command in the configure>router>ospf>area>interface ip-int-name context.
The no form of the command reverts the reference-bandwidth to the default value.
Default reference-bandwidth 100000000 — Reference bandwidth of 100 Gbps.
