Command History
Usage Guidelines Use the auto-cost command to set the reference bandwidth used by the OSPF cost-metric calculation.
The value set by the ip ospf cost command overrides the cost that results from the auto-cost command.
This command requires the LAN Base Services license.
Examples This example shows how to set the reference bandwidth for all local interfaces in an OSPF instance:
switch# configure terminal
switch(config)# router ospf 201
