Setting An Ospf Cost For An Interface - HP HPE FlexNetwork 7500 series Configuration Manual

To configure Type-3 LSA filtering:
Step
1. Enter system view.
2. Enter OSPF view.
3. Enter area view.
4. Configure Type-3 LSA
filtering.

Setting an OSPF cost for an interface

Set an OSPF cost for an interface by using either of the following methods:
•
Set the cost value in interface view.
•
Set a bandwidth reference value for the interface. OSPF computes the cost with this formula:
Interface OSPF cost = Bandwidth reference value (100 Mbps) / Expected interface bandwidth
(Mbps). 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.
If no cost or bandwidth reference value is configured for an interface, OSPF computes the

interface cost based on the interface bandwidth and default bandwidth reference value.
To set an OSPF cost for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Set an OSPF cost for
the interface.
To set a bandwidth reference value:
Step
1. Enter system view.
2. Enter OSPF view.
3. Set a bandwidth
reference value.

By default, the OSPF cost is calculated
according to the interface bandwidth.
For a loopback interface, the OSPF cost
is 0 by default.
