Setting the maximum number of attempts to send an NS message for DAD
About the maximum number of attempts to send an NS message for DAD
An interface sends an NS message for DAD for an obtained IPv6 address. The interface resends the NS message if it does not receive a response within the time specified by the ipv6 nd ns retrans-timer command. If the interface receives no response after making the maximum attempts specified by the ipv6 nd dad attempts command, the interface uses the IPv6 address.
