Configuring ABR Type-3 LSA filtering
You can configure an ABR to filter Type-3 LSAs advertised to an area.

Configuring an OSPF cost for an interface
You can configure an OSPF cost for an interface by using either of the following methods:
• Configure the cost value in interface view
• Configure a bandwidth reference value for the interface. OSPF computes the cost with this formula:
Interface OSPF cost = Bandwidth reference value (100 Mbps)/Interface bandwidth (Mbps). If the
calculated cost is greater than 65,535, the value of 65,535 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.

ospf cost value
Optional.
The default cost depends on the interface
type: 1 for a VLAN interface and 0 for a
loopback interface, computed according
to the bandwidth for other interfaces.
To configure a bandwidth reference value:
