Configuring Type-3 Lsa Filtering; Configuring An Ospf Cost For An Interface - HP 6125XLG Configuration Manual

Step
2. Enter OSPF view.
3. Configure OSPF to
filter routes calculated
using received LSAs.

Configuring 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:
Step
1. Enter system view.
2. Enter OSPF view.
3. Enter area view.
4. Configure Type-3 LSA
filtering.

Configuring an OSPF cost for an interface

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 65535, the value of 65535 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:
Step
1. Enter system view.
2. Enter interface view.
3. Configure an OSPF cost
for the interface.
To configure a bandwidth reference value:
Command
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
filter-policy { acl-number [ gateway
ip-prefix-name ] | gateway ip-prefix-name |
ip-prefix ip-prefix-name [ gateway

route-policy-name } import
Command

Remarks
N/A
By default, OSPF accepts all
routes calculated using
received LSAs.

N/A
By default, the ABR does
not filter Type-3 LSAs.
Remarks

N/A
By default, the OSPF cost is calculated
according to the interface bandwidth. For
a loopback interface, the OSPF cost is 0
by default.
