Mbps.
Description
Use the bandwidth-reference command to specify a reference bandwidth value for
link cost calculation.
Use the undo bandwidth-reference command to restore the default value.
The default value is 100 Mbps.
When links have no cost values configured, OSPF calculates their cost values:
Cost=Reference bandwidth value / Link bandwidth. If the calculated cost is greater than
65535, the value of 65535 is used.
Examples
# Specify the reference bandwidth value as 1000 Mbps.
