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 in order 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

Required
Not ignored by default
Disable Interfaces from Sending OSPFv3 Packets
Follow these steps to disable interfaces from sending OSPFv3 packets:
To do… Use the command… Remarks
Enter system view system-view —
Enter OSPFv3 view ospfv3 [ process-id ] —
Disable interfaces from sending
OSPFv3 packets
silent-interface { interface-type
interface-number | all }
Required
Not disabled by default
z Multiple OSPFv3 processes can disable the same interface from sending OSPFv3 packets. Using
the silent-interface command disables only the interfaces associated with the current process.
z 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.
Therefore, no neighboring relationship can be established on the interface. This feature can
enhance the adaptability of OSPFv3 networking.
