DGS-6604 m auto-cost reference-bandwidth auto-cost reference-bandwidth Use this command to control how OSPF calculates default metrics for the interface.The no form of this command will reset the reference bandwidth to the default value. auto-cost reference-bandwidth MBPS no aut-cost reference-bandwidth Syntax Description MBPS The reference bandwidth in Mbps. The default reference bandwidth is 100 Mbps. The valid setting is 1 to 4294967. Default Command Mode Usage Guideline Example Enabled MBPS: 100 Router configuration By default OSPF calculates the OSPF metric for an interface by dividing the reference bandwidth by the bandwidth of interface. The default value for the reference bandwidth is 100Mbps. For example, a 100Mbps will have a metric of 1 and a 64K link will have a metric of 1562, The auto-cost command is used to differentiate high bandwidth links. For multiple links with high bandwidth, specify a larger reference bandwidth value to differentiate costs on those links. Before the cost is changed to the manual configuration mode, the cost must be configured in advance. This following example shows how to set reference bandwidth to 50 Mbps. Switch# configure terminal Switch(config)# router ospf Switch(config-router)# auto-cost reference-bandwidth 50 Verify the settings by entering the show ip protocol ospf command. CLI Reference Guide 55
