value: OSPF cost, in the range of 0 to 65535 for a loopback interface and 1 to 65535 for other
interfaces.
Description
Use ospf cost to set an OSPF cost for the interface.
Use undo ospf cost to restore the default.
The default cost depends on the interface type: 1 for a VLAN interface; 0 for a loopback interface;
computed according to the bandwidth for other interfaces with the formula: Interface OSPF cost =
Bandwidth reference value (100 Mbps) ÷ Interface bandwidth (Mbps).
If the calculated cost is greater than 65535, the value of 65535 is used; if the calculated cost is smaller
than 1, the value of 1 is used.
