Configuring Abr Type-3 Lsa Filtering; Configuring An Ospf Cost For An Interface - H3C S5800 Series Configuration Manual

Configuring ABR Type-3 LSA Filtering

This task is configured on an ABR to filter Type-3 LSAs to be advertised in the attached non-backbone
area and the Type-3 LSAs to be advertised to other areas.
Follow these steps to configure Type-3 LSA filtering on an ABR:
To do...
Enter system view
Enter OSPF view
Enter area view
Configure ABR Type-3 LSA

Configuring an OSPF Cost for an Interface

You can configure an OSPF cost for an interface with one of the following two methods:
Configure the cost value in interface view.
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:
To do...
Enter system view
Enter interface view
Configure an OSPF cost for
the interface
Follow these steps to configure a bandwidth reference value:
Use the command...
system-view
ospf [ process-id | router-id router-id |
vpn-instance instance-name ] *
area area-id
filter { acl-number | ip-prefix
ip-prefix-name } { import | export }
Use the command...
system-view
interface interface-type
interface-number
ospf cost value

Optional
By default, an interface computes its cost
according to the bandwidth.
The cost value defaults to 0 on loopback
interfaces.
