Usage guidelines

An interface sends an NS message for DAD after obtaining an IPv6 address.

If the interface does not receive a response within the time specified by using ipv6 nd ns retrans-timer, it resends an NS message.

If the interface receives no response after making the maximum sending attempts (set by using ipv6 nd dad attempts), the interface uses the obtained address.

Examples

# Set the number of attempts to send an NS message for DAD to 20.

<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd dad attempts 20
