Configuring a Limit on the Rate at Which NS Messages Are Sent for DAD to Continue Detection in an Address Conflict 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. This limit can be adjusted as required.
