CLI Reference Guide

auto-cost reference-bandwidth

Use this command to control how OSPF calculates the default metric for the

interface.The no form of this command will reset the reference bandwidth to the

default value.

auto-cost reference-bandwidth MBPS

no auto-cost reference-bandwidth

Default Enabled.

MBPS: 100

Command Mode Router configuration.

Usage Guideline 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.

Example This following example shows how to set reference bandwidth to 50 Mbps.

Verify the settings by entering the show ip protocol ospf command.

Syntax Description

MBPS The reference bandwidth in Mbps. The default reference bandwidth is 100 Mbps.

The valid setting is 1 to 4294967.
