[Sysname] interface vlan-interface 100 [Sysname-Vlan-interface100] ipv6 nd ra no-advlinkmtu ipv6 nd ra prefix Use ipv6 nd ra prefix to configure the prefix information in RA messages. Use undo ipv6 nd ra prefix to remove the prefix information from RA messages. Syntax ipv6 nd ra prefix { ipv6-prefix prefix-length | ipv6-prefix/prefix-length } valid-lifetime preferred-lifetime [ no-autoconfig | off-link ] * undo ipv6 nd ra prefix { ipv6-prefix | ipv6-prefix/prefix-length } Default No prefix information is configured for RA messages. Instead, 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 the fixed valid lifetime 2592000 seconds (30 days) and preferred lifetime 604800 seconds (seven days). If the IPv6 address is automatically obtained (through DHCP, for example), the prefix uses the valid and preferred lifetime of the IPv6 address. Views Interface view Predefined user roles network-admin Parameters ipv6-prefix: Specifies the IPv6 prefix. prefix-length: Specifies the prefix length of the IPv6 address. valid-lifetime: Specifies the valid lifetime of a prefix, in the range of 0 to 4294967295 seconds. 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 greater than the valid lifetime. 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. Usage guidelines After hosts on the same link receive RA messages, they can use the prefix information in the RA messages for stateless autoconfiguration.

ipv6 nd ra prefix
Use
ipv6 nd ra prefix
to configure the prefix information in RA messages.
Use
undo ipv6 nd ra prefix
to remove the prefix information from RA messages.
Syntax
ipv6 nd ra prefix
{
ipv6-prefix
prefix-length
|
ipv6-prefix
/
prefix-length
}
valid-lifetime preferred-lifetime
[
no-autoconfig
|

Default
No prefix information is configured for RA messages. Instead, 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 the fixed valid lifetime 2592000 seconds (30
days) and preferred lifetime 604800 seconds (seven days).
If the IPv6 address is automatically obtained (through DHCP, for example), the prefix uses the valid and
preferred lifetime of the IPv6 address.

Parameters
ipv6-prefix
: Specifies the IPv6 prefix.
prefix-length
: Specifies the prefix length of the IPv6 address.
valid-lifetime
: Specifies the valid lifetime of a prefix, in the range of 0 to 4294967295 seconds.
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 greater than the valid lifetime.
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.
Usage guidelines
After hosts on the same link receive RA messages, they can use the prefix information in the RA messages
for stateless autoconfiguration.
