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: 
 
Ste
 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.

1.  Enter system view.

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:
