Configuring The Maximum Number Of Attempts To Send An Ns Message For Dad - HP 6125G Configuration Manual

Step
4. Configure the prefix
information in RA
messages.
5. Turn off the MTU option in
RA messages.
6. Set the M flag bit to 1.
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 specified 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.

Remarks
Optional.
By default, no prefix information is
configured for RA messages, and the
IPv6 address of the interface sending RA
messages is used as the prefix
information with valid lifetime 2592000
seconds (30 days) and preferred lifetime
604800 seconds (seven days).
Optional.
By default, RA messages contain the
MTU option.
Optional.
By default, the M flag bit is set to 0 and
hosts acquire IPv6 addresses through
stateless autoconfiguration.
Optional.
By default, the O flag bit is set to 0 and
hosts acquire other configuration
information through stateless
autoconfiguration.
Optional.
1800 seconds by default.
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.
