ipv6 nd dad attempts
The ipv6 nd dad attempts Interface Configuration mode command configures the number of
consecutive neighbor solicitation messages that are sent on an interface while duplicate address
detection is performed on the unicast IPv6 addresses of the interface. Use the no form of this command
to return the number of messages to the default value.
Syntax
•
ipv6 nd dad attempts attempts-number
•
no ipv6 nd dad attempts
•
attempts-number — The number of neighbor solicitation messages. Configuring a value of 0
disables duplicate address detection 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 (1) neighbor
solicitation message is enabled.
Command Mode
Interface configuration (Ethernet, VLAN, Port-channel). Cannot be configured for a range of
interfaces (range context).
