Step Command Remarks
3. Configure route
summarization on an
ASBR.
asbr-summary
ipv6-address
prefix-length [
cost
cost |
not-advertise
|
nssa-only
|
tag
tag ] *
By default, route summarization is
not configured on an ASBR.
Configuring OSPFv3 received route filtering
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter OSPFv3 view.
ospfv3
[ process-id |
vpn-instance
vpn-instance-name ] *
N/A
3. Configure OSPFv3 to
filter routes calculated
using received LSAs.
filter-policy
{ acl6-number [
gateway
prefix-list-name ] |
prefix-list
prefix-list-name [
gateway
prefix-list-name ] |
gateway
prefix-list-name |
route-policy
route-policy-name }
import
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.
Configuring Inter-Area-Prefix LSA filtering
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter OSPFv3 view.
ospfv3
[ process-id |
vpn-instance
vpn-instance-name ] *
N/A
3. Enter OSPFv3 area view.
area
area-id
N/A
4. Configure OSPFv3 to
filter Inter-Area-Prefix
LSAs.
filter
{ acl6-number |
prefix-list
prefix-list-name |
route-policy
route-policy-name } {
export
|
import
}
By default, OSPFv3 accepts all
Inter-Area-Prefix LSAs.
This command takes effect only
on ABRs.
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 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 configured for an interface, OSPFv3 automatically computes the cost for the
interface.
