Setting The Maximum Number Of Attempts To Send An Ns Message For Dad - HPE FlexNetwork 10500 Series Configuration Manual

Step
3. Configure the prefix
information in RA
messages.
4. Turn off the MTU option in
RA messages.
5. Specify unlimited hops in
RA messages.
6. Set the M flag bit to 1.
7. Set the O flag bit to 1.
8. Set the router lifetime in
RA messages.
9. Set the NS retransmission
timer.
10. Set the router preference
in RA messages.
11. Set the reachable time.
Setting 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 set the attempts to send an NS message for DAD:
Step
1. Enter system view.
Command
ipv6 nd ra prefix { ipv6-prefix

ipv6-prefix/prefix-length }

Remarks
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. 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.
By default, RA messages contain the
MTU option.
By default, the maximum number of
hops in RA messages is 64.
By default, the M flag bit is set to 0 in
RA advertisements. Hosts receiving the
advertisements will obtain IPv6
addresses through stateless
autoconfiguration.
By default, the O flag bit is set to 0 in
RA advertisements. Hosts receiving the
advertisements will acquire other
configuration information through
stateless autoconfiguration.
By default, the router lifetime is 1800
seconds.
By default, an interface sends NS
messages every 1000 milliseconds,
and the value of the Retrans Timer field
in RA messages is 0.
By default, the router preference is
medium.
By default, the neighbor reachable time
is 30000 milliseconds, and the value of
the Reachable Time field in sent RA
messages is 0.
