Configuring OSPFv3 received route filtering
According to some rules, you can configure OSPFv3 to filter routes calculated using received LSAs.
To configure OSPFv3 to filter routes calculated using received LSAs:
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: 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.
To configure an OSPFv3 cost for an interface:
Step Command Remarks
1. Enter system view. system-view N/A
