Configuring The Maximum Number Of Attempts To Send An Ns Message For Dad - HP 830 Series Configuration Manual

Step
7. Set the O flag bit to 1.
8. Configure the router
lifetime in RA messages.
9. Set the NS retransmission
timer.
10. Set the reachable time.
Configuring the maximum number of attempts to send an NS
message for DAD
An interface sends an NS message for DAD after acquiring an IPv6 address. If the interface does not
receive a response within a specific time (determined by the ipv6 nd ns retrans-timer command), it
continues to send an NS message. If the interface still does not receive a response after the number of
sent attempts reaches the threshold (specified with the ipv6 nd dad attempts command), the acquired
address is considered usable.
To configure the attempts to send an NS message for DAD:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the number of
attempts to send an NS
message for DAD.

Remarks
Optional.
By default, the O flag bit is set to 0 and
hosts acquire other configuration
information through stateless
autoconfiguration.
Optional.
The default setting is 1800 seconds.
Optional.
By default, the local interface sends NS
messages at 1000 millisecond intervals,
and the value of the Retrans Timer field
in RA messages sent by the local
interface is 0. The interval for
retransmitting an NS message is
determined by the receiving device.
Optional.
By default, the neighbor reachable time
on the local interface is 30000
milliseconds, and the value of the
Reachable Time field in the RA messages
sent by the local interface is 0. The
neighbor reachable time is determined
by the receiving device.
