36.11 ipv6 nd dad attempts

Use the ipv6 nd dad attempts Interface Configuration (Ethernet, VLAN,
Port-channel) mode command to configure the number of consecutive neighbor
solicitation messages that are sent on an interface while Duplicate Address
Detection (DAD) is performed on the unicast IPv6 addresses of the interface. Use
the no form of this command to restore the number of messages to the default
value.
Syntax
ipv6 nd dad attempts
Parameters
attempts—Specifies the number of neighbor solicitation messages. A value of 0
disables DAD processing on the specified interface. A value of 1 configures a
single transmission without follow-up transmissions. (Range: 0–600)
Default Configuration
Duplicate Address Detection on unicast IPv6 addresses with the sending of one
neighbor solicitation message is enabled.
Command Mode
Interface Configuration (Ethernet, VLAN, Port-channel) mode. It cannot be
configured for a range of interfaces (range context).
User Guidelines
Duplicate Address Detection (DAD) verifies the uniqueness of new unicast IPv6
addresses before the addresses are assigned to interfaces (the new addresses
remain in a tentative state while DAD is performed). DAD uses neighbor solicitation
messages to verify the uniqueness of unicast IPv6 addresses.
