3.6.4 Ignoring MTU Check for DD Packets
When LSAs are few in DD packets, it is unnecessary to check 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 instance-id ]
Required
Not ignored by default
3.6.5 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
 Note:
z Multiple processes can disable the same interface from sending OSPFv3 packets.
Using the silent-interface command disables only the interfaces associated with
the current process rather than interfaces associated with other processes.
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.
3.6.6 Enable the Logging on Neighbor State Changes
Follow these steps to enable the logging on neighbor state changes:
