valid-lifetime: Specifies the valid lifetime of a prefix, in the range of 0 to 4294967295 seconds. The
default value is 2592000 seconds (30 days).
preferred-lifetime: Specifies the preferred lifetime of a prefix used for stateless autoconfiguration, in
the range of 0 to 4294967295 seconds. The preferred lifetime cannot be longer than the valid lifetime.
The default value is 604800 seconds (7 days).
no-autoconfig: Specifies a prefix not to be used for stateless autoconfiguration. If you do not specify
this keyword, the prefix is used for stateless autoconfiguration.
off-link: Indicates that the address with the prefix is not directly reachable on the link. If you do not
specify this keyword, the address with the prefix is directly reachable on the link.
no-advertise: Disables the device from advertising the prefix specified in this command. If you do
not specify this keyword, the device advertises the prefix specified in this command.
Usage guidelines
After hosts on the same link receive RA messages, they can use the prefix information in the RA
messages for stateless autoconfiguration.
A prefix specified without a parameter in this command preferentially uses the default settings
configured by using the ipv6 nd ra prefix default command. If the default settings are unavailable,
the prefix uses the following settings:
• Valid lifetime of 2592000 seconds (30 days).
• Preferred lifetime of 604800 seconds (7 days).
• The prefix is used for stateless autoconfiguration.
• The address with the prefix is directly reachable on the link.
• The prefix is advertised in RA messages.
Examples
# Configure the prefix information in RA messages on VLAN-interface 100.
Method 1:
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ra prefix 2001:10::100/64 100 10
Method 2:
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ra prefix 2001:10::100 64 100 10
ipv6 nd ra prefix default
Use ipv6 nd ra prefix default to configure the default settings for prefixes advertised in RA
messages.
Use undo ipv6 nd ra prefix default to restore the default.
Syntax
ipv6 nd ra prefix default [ valid-lifetime preferred-lifetime [ no-autoconfig | off-link ] * |
no-advertise ]
undo ipv6 nd ra prefix default
Default
No default settings are configured for prefixes advertised in RA messages.
