Command Reference IPv6 Commands
ipv6 nd prefix default
Set the default parameters to be used by the interface. If no parameter is specified for an added
prefix, the parameters set with ipv6 nd prefix default will be used. Note that after a parameter is
specified for the prefix, the default configuration will not be used. That is to say, the configuration of
the prefix cannot be modified with ipv6 nd prefix default; only the prefix that uses all the default
configurations can be modified with this command.
at valid-date preferred-date
The valid lifetime of a prefix can be specified in two ways. One way is to specify a fixed time for each
prefix in the RA; the other way is to specify the end time (in this mode, the valid lifetime of the prefix
sent in RA will be gradually reduced until the end time is 0).
The following example adds a prefix for SVI 1.
Ruijie(config)# interface vlan 1
Ruijie(conifig-if)# ipv6 nd prefix 2001::/64 infinite 2592000
The following example sets the default prefix parameters for SVI 1 (they cannot be used for auto
address configuration):
Ruijie(config)# interface vlan 1
Ruijie(config-if)# ipv6 prefix default no-autoconfig
If no parameter is specified, the default parameters will be used, and the prefix cannot be used for
auto address configuration.
Displays the RA information of an interface.
Use this command to set the hopcount of the RA message. Use the no form of this command to
restore the default setting.
