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.
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 router-lifetime
Use ipv6 nd ra router-lifetime to configure the router lifetime in RA messages.
Use undo ipv6 nd ra router-lifetime to restore the default.
Syntax
ipv6 nd ra router-lifetime value
undo ipv6 nd ra router-lifetime
Default
The router lifetime in RA messages is 1800 seconds.
