Configure a DR priority.

Optional.
By default, the DR priority is 1.
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 to improve
efficiency.
To ignore MTU check for DD packets:

Not ignored by default.
Disabling interfaces from receiving and sending OSPFv3
packets
Follow these guidelines when you disable interfaces from receiving and sending OSPF 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.
