• Use an ACL or IP prefix list to filter routing information by destination address and meanwhile use
the gateway keyword to filter routing information by next hop.
• Use a routing policy to filter routing information.
For more information about IP prefix list and routing policy, see "Configuring routing policies."
To configure inbound route filtering:
Ste

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 ] *

3. Configure OSPF to
filter inbound route.

Configuring ABR Type-3 LSA filtering
Perform this task to filter Type-3 LSAs advertised to an area on an ABR.
To configure Type-3 LSA filtering on an ABR:

2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *

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 }

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.
To configure an OSPF cost for an interface:
