Command Reference IPv6 Commands
Use this command to configure the address prefix included in the RA. Use the no form of this
command to delete the set prefix or restore the default setting.
ipv6 nd prefix { ipv6-prefix/prefix-length | default } [ [ valid-lifetime preferred-lifetime ] | [ at valid-date
preferred-date ] | [ infinite | preferred-lifetime ] ] [ no-advertise] | [ [ off-link ] [ no-autoconfig ] ] |
[ pool pool-name ] ]
no ipv6 nd prefix { ipv6-prefix/prefix-length | default }
IPv6 network ID following the format defined in RFC4291
Length of the IPv6 prefix. “/” shall be added in front of the prefix
Valid lifetime of the RA prefix received by the host
Preferred lifetime of the RA prefix received by the host
at valid-date preferred-date
Sets the dead line for the valid lifetime and that of the preferred
lifetime, in day, month, year, hour, minute.
Indicates that the prefix is always valid.
The prefix will not be advertised by the device.
When the host sends an IPv6 packet, if the prefix of the destination
address matches the set prefix, it is considered that the destination is
on-link and is directly reachable. If this option is set, it indicates that
the prefix is not used for on-link judgment.
Indicates that the RA prefix received by the host cannot be used for
auto address configuration.
Indicates the IPv6 prefix pool
By default, the advertised prefix is the one set with ipv6 address on the interface. The default
parameters of the prefix configured in the RA are as follows:
valid-lifetime: 2592000s (30 days)
preferred-lifetime: 604800s (7 days),
The prefix is advertised and is used for on-link judgment and auto address configuration.
Interface configuration mode.
This command can be used to configure the parameters of each prefix, including whether to advertise
the prefix. By default, the prefix advertised in RA is the one set with ipv6 address on the interface. To
add other prefixes, use this command.
