Configuring Inter-Area-Prefix Lsa Filtering; Setting An Ospfv3 Cost For An Interface - HP HPE FlexNetwork 7500 series Configuration Manual

Step
3. Configure OSPFv3 to
filter routes calculated
using received LSAs.

Configuring Inter-Area-Prefix LSA filtering

Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enter OSPFv3 area view.
4. Configure OSPFv3 to
filter Inter-Area-Prefix
LSAs.

Setting an OSPFv3 cost for an interface

You can set an OSPFv3 cost for an interface with one of the following methods:
•
Set the cost value in interface view.
•
Set a bandwidth reference value for the interface, and OSPFv3 computes the cost
automatically based on the bandwidth reference value by using the following formula:
Interface OSPFv3 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 smaller than 1, the value of 1 is used.

•
If no cost is set for an interface, OSPFv3 automatically computes the cost for the interface.
To set an OSPFv3 cost for an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Set an OSPFv3 cost for the
interface.
To set a bandwidth reference value:

Remarks
By default, OSPFv3 accepts all
routes calculated using received
LSAs.
This command can only filter
routes computed by OSPFv3.
Only routes not filtered out can be
added into the local routing table.

By default, OSPFv3 accepts all
Inter-Area-Prefix LSAs.
This command takes effect only
on ABRs.

By default, the OSPFv3 cost is 1 for
a VLAN interface, is 0 for a loopback
interface. The OSPFv3 cost is
automatically computed according
to the interface bandwidth for other
interfaces.
