The ipv6 nd dad detect rate-limit command configures a limit on the rate at which NS messages are sent for DAD to continue detection in an address conflict self-recovery scenario.
The undo ipv6 nd dad detect rate-limit command restores the default configuration.
By default, the limit on the rate at which NS messages are sent for DAD to continue detection in an address conflict self-recovery scenario is 50 messages per second.
Usage Scenario
When DAD detects an address conflict on an interface, the IPv6 protocol status of the interface becomes down. The interface can go up only after being manually shut down and then restarted. To address this issue, deploy address conflict self-recovery. After detecting an IPv6 address conflict, DAD continues detection until the conflict is removed and the IPv6 protocol status of the interface becomes up. By default, address conflict self-recovery is enabled, and the limit on the rate at which NS messages are sent for DAD to continue detection is 50 messages per second. To adjust this limit, run the ipv6 nd dad detect rate-limit command.
