NOTE:
•
The dead interval set on neighboring interfaces cannot be too short. Otherwise, a neighbor is easily
considered down.
• The LSA retransmission interval cannot be too short; otherwise, unnecessary retransmissions occur.
Configuring a DR priority for an interface
To configure 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.
By default, the DR
priority is 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 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
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
