Configuring a DR priority for an interface
The router priority is used for DR election. Interfaces having the priority 0 cannot become a DR or BDR.
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 router priority.
ospfv3 dr-priority priority [ instance
instance-id ] The default router priority
is 1.
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.
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 ] By default, OSPFv3 does not
ignore MTU check for DD packets.
Disabling interfaces from receiving and sending OSPFv3
packets
After an OSPFv3 interface is set to silent, direct routes of the interface can still be advertised in
Intra-Area-Prefix LSAs through 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.
