information. If the IPv6 address is
manually configured, the prefix uses a
fixed valid lifetime of 2592000 seconds
(30 days) and a preferred lifetime of
604800 seconds (7 days). If the IPv6
address is automatically obtained, the
prefix uses the valid lifetime and
preferred lifetime configured for the
IPv6 address.

Configuring 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.
To configure the attempts to send an NS message for DAD:
