1-3 

2: System level 

value: Bandwidth reference value for link cost calculation, in the range 1 to 2147483648 Mbps. 

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. 

You can configure an OSPFv3 cost for an interface with one of the following two methods: 

z 

Configure the cost value in interface view. 

z 

Configure a bandwidth reference value, and OSPFv3 computes the cost automatically based on 

the bandwidth reference value: Interface OSPFv3 cost = Bandwidth reference value/Interface 

bandwidth. If the calculated cost is greater than 65535, the value of 65535 is used.  

If no cost value is configured for an interface, OSPFv3 computes the interface cost value automatically: 

# Specify the reference bandwidth value as 1000 Mbps.

2: System level 

value: Specifies a default cost for redistributed routes, in the range of 1 to 16777214.  

Use the default cost command to configure a default cost for redistributed routes.  

Use the undo default cost command to restore the default.  

By default, the default cost is 1. 

You need to configure the default cost value for redistributed routes to advertise them throughout the 

whole AS.
