Step Command Remarks
3. Configure inbound
route filtering.

Configuring ABR Type-3 LSA filtering
You can configure an ABR to filter Type-3 LSAs advertised to an area.
To configure Type-3 LSA filtering on an ABR:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
N/A
3. Enter area view. area area-id N/A
4. Configure ABR Type-3 LSA
filtering.
filter { acl-number | ip-prefix
ip-prefix-name } { import | export } Not configured by
default
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 ÷ Interface bandwidth. 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 is configured for an interface, OSPF computes the interface cost automatically.
To configure an OSPF cost for an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an OSPF cost
for the interface.
ospf cost value
Optional.
By default, an interface computes its cost
according to the bandwidth.
The cost value defaults to 0 on loopback
interfaces.
To configure a bandwidth reference value:
