ipv6 nd dad attempts

This command configures the number of duplicate address detection (DAD) attempts made on the
interface when configuring IPv6 unicast addresses.
Syntax
ipv6 nd dad attempts number

Parameters
number
Defaults
Duplicate address detection enabled, for 1 attempt.
Mode
Router interface configuration: G3(su)‐>router(Config‐if(Vlan 1))#
Usage
IPv6 Duplicate Address Detection is described in RFC 2462. Duplicate Address Detection uses
Neighbor Solicitation and Neighbor Advertisement messages to verify the uniqueness of an
address. Duplicate Address Detection must be performed on unicast addresses prior to assigning
them to an interface. An address remains in a tentative state while Duplicate Address Detection is
being performed. If a tentative address is found to be a duplicate, an error message is returned
and the address is not assigned to the interface.
Use this command to change the number of Neighbor Solicitation messages that can be sent for
Duplicate Address Detection from the default value of 1. The no form of the command returns the
value to the default of 1. A value of 0 disables Duplicate Address Detection on the interface.
The show ipv6 interface command displays the current DAD attempt setting.
Specifies the number of consecutive Neighbor Solicitation message
transmitted on the interface, when Duplicate Address Detection (DAD)
is performed on a unicast IPv6 address assigned to the interface.
The value can range from 0 to 600. A value of 0 disables Duplicate
Address Detection on the interface. A value of 1, which is the default,
specifies a single transmission with no follow‐up transmissions.
