AUTO-COST REFERENCE-BANDWIDTH
Syntax
auto-cost reference-bandwidth <1-4294967>
no
auto-cost reference-bandwidth
Parameters
reference-bandwidth
Specifies the reference bandwidth in Mbits per
second.
Description
Use the AUTO-COST REFERENCE-BANDWIDTH command to control
how OSPF calculates default metrics for the interface. The reference
bandwidth is measured by Mbits per second. The default value for the
reference bandwidth is 100Mbps.
By default, OSPF calculates the OSPF metric for an interface by dividing
the reference bandwidth by the interface bandwidth. This command is
used to differentiate high bandwidth links. For multiple links with high
bandwidth, specify a larger reference bandwidth value to differentiate cost
on those links.
Use the no form of this command to assign cost, based only on the
interface bandwidth.
Command Mode
Router mode
Example
The following commands set the reference bandwidth to 50 Mbits per
second:
switch#configure terminal
switch(config)#router ospf 100
switch
(config-router)# auto-cost reference-bandwidth
50
