reference-bandwidth
Syntax reference-bandwidth reference-bandwidth
no reference-bandwidth
Context config>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:
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
config>router>ospf>area>interface ip-int-name context.
The no form of the command reverts the reference-bandwidth to the default value.
