Default Cost - 3Com S7906E Command Reference Manual

Default Level
2: System level
Parameters
value: Bandwidth reference value for link cost calculation, in the range 1 to 2147483648 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.
You can configure an OSPFv3 cost for an interface with one of the following two methods:
Configure the cost value in interface view.
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:
Examples
# Specify the reference bandwidth value as 1000 Mbps.
<Sysname> system-view
[Sysname] ospfv3 1
[Sysname-ospfv3-1] bandwidth-reference 1000
