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. 

# Specify the reference bandwidth value as 1000 Mbps.
