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 computes the interface cost value
automatically.
To configure an OSPFv3 cost for an interface:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure an OSPFv3
cost for the interface.
To configure a bandwidth reference value:
Step
1.
Enter system view.
2.
Enter OSPFv3 view.
3.
Configure a bandwidth
reference value.
Configuring the maximum number of OSPFv3 ECMP routes
Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:
Command
filter-policy { acl-number | ipv6-prefix
ipv6-prefix-name } import
Command
system-view
interface interface-type
interface-number
ospfv3 cost value [ instance
instance-id ]
Command
system-view
ospfv3 [ process-id ]
bandwidth-reference value
213
Remarks
Not configured by default.
The filter-policy import command
can only filter routes computed by
OSPFv3. Only routes not filtered
out can be added into the local
routing table.

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.
