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
