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.
407B
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.
408B
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.
ospfv3 [ process-id | vpn-instance
vpn-instance-name ] *
N/A
3. Disable interfaces from
receiving and sending
OSPFv3 packets.
silent-interface { interface-type
interface-number | all }
By default, the interfaces are able
to receive and send OSPFv3
packets.
This command disables only the
interfaces associated with the
current process, though multiple
OSPFv3 processes can disable the
same interface from receiving and
sending OSPFv3 packets.
