Usage
IPv6DuplicateAddressDetectionisdescribedinRFC2462.DuplicateAddressDetectionuses
NeighborSolicitationandNeighborAdvertisementmessagestoverifytheuniquenessofan
address.DuplicateAddressDetectionmustbeperformedonunicastaddressespriortoassigning
themtoaninterface.AnaddressremainsinatentativestatewhileDuplicate
AddressDetectionis
beingperformed.Ifatentativeaddressisfoundtobeaduplicate,anerrormessageisreturned
andtheaddressisnotassignedtotheinterface.
UsethiscommandtochangethenumberofNeighborSolicitationmessagesthatcanbesentfor

valueof1.Thenoformofthecommandreturnsthe
valuetothedefaultof1.Avalueof0disablesDuplicateAddressDetectionontheinterface.

whenDuplicateAddressDetection(DAD)
isperformedonaunicastIPv6addressassignedtotheinterface.
Thevaluecanrangefrom0to600.Avalueof0disablesDuplicate
