Configuring a DR priority for an interface
Follow these steps to configure a DR priority for an interface:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view interface interface-type interface-number —
Configure a DR priority ospfv3 dr-priority priority [ instance instance-id ]
Optional
Defaults to 1
NOTE:
The DR priority of an interface determines the interface’s qualification in DR election. Interfaces having the
priority 0 cannot become a DR or BDR.
Ignoring MTU check for DD packets
When LSAs are few in DD packets, it is unnecessary to check the MTU in DD packets to improve
efficiency.
Follow these steps to ignore MTU check for DD packets:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view
interface interface-type
interface-number
—
Ignore MTU check for DD packets
ospfv3 mtu-ignore [ instance
instance-id ] Required
Not ignored by default
Disable interfaces from receiving and sending OSPFv3 packets
Follow these steps to disable interfaces from receiving and sending OSPFv3 packets:
To do… Use the command… Remarks
Enter system view system-view —
Enter OSPFv3 view ospfv3 [ process-id ] —
Disable interfaces from receiving
and sending OSPFv3 packets silent-interface { interface-type
interface-number | all } Required
Not disabled by default
NOTE:
•
Multiple OSPFv3 processes can disable the same interface from receiving and sending OSPFv3 packets.
Using the silent-interface command disables only the interfaces associated with the current process.
• After an OSPF interface is set to silent, direct routes of the interface can still be advertised in
Intra-Area-Prefix-LSAs via other interfaces, but other OSPFv3 packets cannot be advertised. No
neighboring relationship can be established on the interface. This feature can enhance the adaptability
of OSPFv3 networking.
