Command Remarks
1. Enter system view.
system-view N/A
2. Enter OSPFv3 view.

3. Configure inbound
route filtering.
filter-policy { acl-number | ipv6-prefix
ipv6-prefix-name } import
Not configured by default.
NOTE:
The filter-policy import command can only filter routes computed by OSPFv3. Only routes not filtered ou

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
65535, the value of 65535 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.

N/A
3. Configure an OSPFv3
cost for the interface.
ospfv3 cost value [ instance
instance-id ]
Optional.
The default cost depends on the interface type:
1 for a VLAN interface; 0 for a loopback
interface; computed according to the
bandwidth for other interfaces.

Configuring the maximum number of OSPFv3 ECMP routes
Perform this task to implement load sharing over ECMP routes.
