Configuring Ospfv3 Inbound Route Filtering; Configuring An Ospfv3 Cost For An Interface - HPE 5800 Series Configuration Manual

Configuring route summarization on an ASBR
Perform this task to enable an ASBR to summarize external routes within the specified address
range into a single route.
An ASBR can summarize routes in the following LSAs:
•
Type-5 LSAs.
•
Type-7 LSAs in an NSSA area.
•
Type-5 LSAs translated by the ASBR (also an ABR) from Type-7 LSAs in an NSSA area.
If the ASBR (ABR) is not a translator, it cannot summarize routes in Type-5 LSAs translated
from Type-7 LSAs.
To configure route summarization on an ASBR:
Step
Enter system view.
1.
Enter OSPFv3 view.

Configuring OSPFv3 inbound route filtering

According to some rules, you can configure OSPFv3 to filter routes that are computed from received
LSAs.
To configure OSPFv3 inbound route filtering:
Step
Enter system view.
1.
Enter OSPFv3 view.
2.
Configure inbound

route filtering.
NOTE:
The filter-policy import command can only filter routes computed by OSPFv3. Only routes not
filtered out can be added into the local routing table.

Configuring an OSPFv3 cost for an interface

You can configure an OSPFv3 cost for an interface with one of the following methods:
•
Configure the cost value in interface view.
•
Configure a bandwidth reference value for the interface, and OSPFv3 computes the cost
automatically based on the bandwidth reference value: Interface OSPFv3 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 smaller than 1, the value of 1 is
used.
If the cost value is not configured for an interface, OSPFv3 automatically computes the interface cost
value.
