Description
Use ospfv3 cost to configure the OSPFv3 cost of the interface in an instance.
Use undo ospfv3 cost to restore the default OSPFv3 cost of the interface in an instance.
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 with the formula: Interface OSPF 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.
Examples
# Specifies the OSPFv3 cost of the interface in instance 1 as 33.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospfv3 cost 33 instance 1
ospfv3 dr-priority
Syntax
ospfv3 dr-priority priority [ instance instance-id ]
undo ospfv3 dr-priority [ priority ] [ instance instance-id ]
View
Interface view
Default level
2: System level
Parameters
priority: DR priority, in the range of 0 to 255.
instance-id: ID of the instance an interface belongs to, in the range of 0 to 255, which defaults to 0.
Description
Use ospfv3 dr-priority to set the DR priority for an interface in an instance.
Use undo ospfv3 dr-priority to restore the default value.
The DR priority on an interface defaults to 1.
An interface’s DR priority determines its privilege in DR/BDR selection, and the interface with the highest
priority is preferred.
Examples
# Set the DR priority for an interface in instance 1 to 8.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospfv3 dr-priority 8 instance 1
