The ipv6 nd dad detect attempts command configures a threshold for DAD to consider an address available in an address conflict self-recovery scenario.
The undo ipv6 nd dad detect attempts command restores the default configuration.
By default, the threshold for DAD to consider an address available in an address conflict self-recovery scenario is 3.
Usage Scenario
If an address conflict occurs on an interface in an address conflict self-recovery scenario, DAD continues detection on the interface until the address conflict is removed. The device considers the address conflict removed when DAD does not receive conflict packets for a specified number of consecutive times. This number, referred to as the address conflict removal threshold, can be configured using the ipv6 nd dad detect attempts command. In this case, DAD considers the address available. Otherwise, DAD considers the address unavailable and continues detection.
