ospf cost

Syntax ospf cost value

undo ospf cost

View Interface view

Parameters value: Value of OSPF cost, in the range 1 to 65535.

Description Use the ospf cost command to set an OSPF cost for the interface.

Use the undo ospf cost command to restore the default OSPF cost for the interface.

By default, an OSPF interface calculates its cost with the formula: interface default OSPF cost=100 Mbps/interface bandwidth(Mbps). Default OSPF costs of some interfaces are:

■1785 for the 56kbps serial interface

■1562 for the 64kbps serial interface

■48 for the E1 (2.048Mbps) interface

■1 for the Ethernet interface

You can use the ospf cost command to set an OSPF cost for an interface manually.

This configuration is not supported on the NULL interface.

Examples # Set the OSPF cost for the interface to 65.
