Use the following commands to configure IPv6 Neighbor Discovery settings.
Command
Purpose
ipv6 nd prefix 
prefix/prefix-length
 
[{
valid-lifetime
infinite} {
preferred-
lifetime
infinite}] 
[no-autoconfig] [off-
link]
Configure parameters associated with network prefixes that 
the router advertises in its Neighbor Discovery 
advertisements. 
• ipv6-prefix—IPv6 network prefix.
prefix-length
—IPv6 network prefix length.
valid-lifetime
—Valid lifetime of the router in seconds. 
(Range: 0–4294967295 seconds.)
• infinite—Indicates lifetime value is infinite.
preferred-lifetime
—Preferred-lifetime of the router in 
seconds. (Range: 0–4294967295 seconds.)
• no-autoconfig—Do not use the prefix for auto 
configuration.
• off-link—Do not use the prefix for onlink determination.
ipv6 nd ra-interval 
maximum
 
minimum
Set the transmission interval between router Neighbor 
Discovery advertisements.
maximum
 — The maximum interval duration (Range: 
4–1800 seconds).
minimum
 — The minimum interval duration (Range: 3 – 
(0.75 * maximum) seconds).
ipv6 nd ra-lifetime 
seconds
Set the value that is placed in the Router Lifetime field of 
the router Neighbor Discovery advertisements sent from the 
interface.
The 
seconds 
value must be zero, or it must be an integer 
between the value of the router advertisement transmission 
interval and 9000 seconds. A value of zero means this router 
is not to be used as the default router. (Range: 0-9000).
ipv6 nd suppress-ra
Suppress router advertisement transmission on an interface.
ipv6 nd dad attempts 
value
Set the number of duplicate address detection probes 
transmitted while doing Neighbor Discovery. 
The range for 
value 
is 0–600.
