8. Set the O flag bit to 1.
ipv6 nd autoconfig other-flag

ipv6 nd ra router-lifetime time
By default, the router lifetime is 1800 seconds.
10. Set the NS retransmission timer.
ipv6 nd ns retrans-timer value
By default, an interface sends NS messages every 1000 milliseconds, and the value of the
Retrans Timer field in RA messages is 0.
11. Set the router preference in RA messages.
ipv6 nd router-preference { high | low | medium }
By default, the router preference is medium.

Time field in sent RA messages is 0.
Setting the maximum number of attempts to send
an NS message for DAD
About 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.
Procedure
1. Enter system view.
system-view
2. Enter interface view.

3. Set the number of attempts to send an NS message for DAD.
ipv6 nd dad attempts interval
The default setting is 1. When the interval argument is set to 0, DAD is disabled.
Configuring ND snooping
About ND snooping
The ND snooping feature is used in Layer 2 switching networks. It learns the source MAC addresses,
source IPv6 addresses, input interfaces, and VLANs of arriving ND messages and data packets to
build the ND snooping table.
ND snooping entries can be used by ND detection to prevent spoofing attacks.
