auto-cost
By default, OSPF computes the link cost of each interface from the interface
bandwidth. The link cost is computed as the ratio of a “reference bandwidth”
to the interface bandwidth (ref_bw / interface bandwidth), where interface
bandwidth is defined by the “bandwidth” command. Because the default
reference bandwidth is 100 Mbps, OSPF uses the same default link cost for all
interfaces whose bandwidth is 100 Mbps or greater. To change the reference
bandwidth, use the auto-cost command, specifying the reference bandwidth
in megabits per second. The different reference bandwidth can be
independently configured for OSPFv2 and OSPFv3.
