Parameters
value: Specifies the bandwidth reference value for link cost calculation, in the range of 1 to 4294967
Mbps.
Usage guidelines
If no cost values are configured for links, OSPF calculates their cost values by using the formula: Cost =
Reference bandwidth value / Expected interface bandwidth. The expected bandwidth of an interface is
configured with the bandwidth command (see Interface Command Reference). If the calculated cost is
greater than 65535, the value of 65535 is used. If the calculated cost is less than 1, the value of 1 is used.
The default cost values of common interfaces are as follows:
For a 56 kbps serial interface, the value is 1785.
•
For a 64 kbps serial interface, the value is 1562.
•
• For an E1 (2.048 Mbps) interface, the value is 48.
For an Ethernet (100 Mbps) interface, the value is 1.
•
For a loopback interface, the value is 0.
•
Examples
# Specify the reference bandwidth value as 1000 Mbps.
