Step Command Remarks
4. Set the maximum and
minimum intervals for
sending RA messages.
ipv6 nd ra interval
max-interval min-interval
By default, the maximum interval for
sending RA messages is 600 seconds,
and the minimum interval is 200
seconds.
The device sends RA messages at
random intervals between the maximum
interval and the minimum interval.
The minimum interval should be less

Step Command Remarks
1. Enter system view.

3. Configure the prefix
information in RA
messages.
ipv6 nd ra prefix
{ ipv6-prefix
prefix-length |
ipv6-prefix/prefix-length }
valid-lifetime preferred-lifetime
[
no-autoconfig
|
off-link
] *
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.
4. Turn off the MTU option in
RA messages.
ipv6 nd ra no-advlinkmtu
By default, RA messages contain the
MTU option.
5. Specify unlimited hops in
RA messages.
ipv6 nd ra hop-limit
unspecified
By default, the maximum number of
hops in RA messages is 64.
6. Set the M flag bit to 1.
ipv6 nd autoconfig
managed-address-flag
By default, the M flag bit is set to 0 in
RA advertisements. Hosts receiving the
advertisements will obtain IPv6
addresses through stateless
autoconfiguration.
7. Set the O flag bit to 1.
ipv6 nd autoconfig other-flag
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.
8. Set the router lifetime in
RA messages.
ipv6 nd ra router-lifetime
time
By default, the router lifetime is 1800
seconds.
9. 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.
10. Set the router preference
in RA messages.
ipv6 nd router-preference
{
high
|
low
|
medium
}
By default, the router preference is
medium.
11. Set the reachable time.
ipv6 nd nud reachable-time
By default, the neighbor reachable time
