Follow these steps to configure route summarization between areas:
To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Configure a summary route
The abr-summary command is available on ABRs only. If contiguous network
segments are available in an area, you can use the command to summarize them
into one network segment on the ABR. The ABR will advertise only the summary
route. Any LSA falling into the specified network segment will not be advertised,
reducing the LSDB size in other areas.
You can configure OSPFv3 to filter routes that are computed from received LSAs
according to some rules.
Follow these steps to configure inbound route filtering:
To do...
Enter system view
Enter OSPFv3 view
Configure inbound route
filtering
Use of the filter-policy import command can only filter routes computed by
OSPFv3. Only routes not filtered can be added into the local routing table.
You can configure OSPFv3 link costs for interfaces to adjust routing calculation.
Follow these steps to configure the link cost for an OSPFv3 interface:
To do...
Enter system view
Enter interface view
Configure the cost for the
interface
Use the command...
system-view
ospfv3 [ process-id ]
area area-id
abr-summary ipv6-address
prefix-length
[ not-advertise ]
Use the command...
system-view
ospfv3 [ process-id ]
filter-policy { acl-number |
ipv6-prefix
ipv6-prefix-name } import
Use the command...
system-view
interface interface-type
interface-number
ospfv3 cost value [ instance
instance-id ]
