Duplicate Address Detection Attempts Overview

The duplicate address detection feature helps to verify that a new unicast IPv6 address is unique in the network. The router sends the IPv6 address in its neighbor solicitation messages. However, the router relies on the receiving device to understand the address duplication and does not prompt a conflict if the address already exists.

The CLI allows you to specify the number of consecutive neighbor solicitation messages that the router sends from the IPv6 interface.
