9-14The DR priority of an interface determines the interface’s qualification in DR election. Interfaces havingthe priority 0 cannot become a DR or BDR.Ignoring MTU Check for DD PacketsWhen LSAs are few in DD packets, it is unnecessary to check the MTU in DD packets in order toimprove efficiency.Follow these steps to ignore MTU check for DD packets:To do… Use the command… RemarksEnter system view system-view —Enter interface view interface interface-typeinterface-number —Ignore MTU check for DD packets ospfv3 mtu-ignore [ instanceinstance-id ]RequiredNot ignored by defaultDisable Interfaces from Sending OSPFv3 PacketsFollow these steps to disable interfaces from sending OSPFv3 packets:To do… Use the command… RemarksEnter system view system-view —Enter OSPFv3 view ospfv3 [ process-id ] —Disable interfaces from sendingOSPFv3 packetssilent-interface { interface-typeinterface-number | all }RequiredNot disabled by defaultz Multiple OSPFv3 processes can disable the same interface from sending OSPFv3 packets. Usingthe silent-interface command disables only the interfaces associated with the current process.z After an OSPF interface is set to silent, direct routes of the interface can still be advertised inIntra-Area-Prefix-LSAs via other interfaces, but other OSPFv3 packets cannot be advertised.Therefore, no neighboring relationship can be established on the interface. This feature canenhance the adaptability of OSPFv3 networking.
