Configuring a DR priority for an interface
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view. interface interface-type interface-number N/A
3. Configure a DR priority. ospfv3 dr-priority priority [ instance instance-id ]
Optional.
1 by default.
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 in order to improve
efficiency.
To ignore MTU check for DD packets:
Step Command Remarks
1. Enter system view system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Ignore MTU check for DD
packets.
ospfv3 mtu-ignore [ instance
instance-id ]
Not ignored by default.
Disabling interfaces from receiving and sending OSPFv3
packets
Follow these guidelines when you disable interfaces from receiving and sending OSPFv3 packets:
• 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.
To disable interfaces from receiving and sending OSPFv3 packets:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPFv3 view. ospfv3 [ process-id ] N/A
