Follow these steps to configure Type-3 LSA filtering on an ABR: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id | router-id router-id | 
vpn-instance instance-name ] * 

— 

Enter area view 

area area-id 

— 

Configure ABR Type-3 LSA 
filtering 

filter { acl-number | ip-prefix 
ip-prefix-name } { import | export } 

Required 

Not configured by 
default. 

 

You can configure an OSPF cost for an interface with one of the following two methods: 

z 

Configure the cost value in interface view. 

z 

Configure a bandwidth reference value for the interface, and OSPF computes the cost 

automatically based on the bandwidth reference value: 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. 

Follow these steps to configure an OSPF cost for an interface: 

Enter system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

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. 

 

Follow these steps to configure a bandwidth reference value: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id | router-id router-id | 
vpn-instance instance-name ] * 

— 

Configure a bandwidth 
reference value 

bandwidth-reference value 

Optional 

The value defaults to 
100 Mbps.
