undo ipv6 nd ra prefix { ipv6-prefix | ipv6-prefix

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 (7 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. 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.
prefix-preference level
: Specifies the prefix preference. The
level
argument specifies
the preference value in the range of 0 to 255. A larger value indicates a higher preference. The
client selects an IPv6 prefix with the highest preference for address generation. If you do not specify
this option, the RA message does not carry the preference for the prefix.
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.
