Information
By default, all prefixes configured as addresses on the interface are advertised. This command allows
control over the individual parameters per prefix; you can use the default keyword to use the default
parameters for all prefixes. If a prefix has been configured with lifetime parameter values, the default
values cannot be applied using the ipv6 nd prefix default no-autoconfig command.
