Usage 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. Use this command in the Configuration
Terminal Batch mode to advertise in a dual-homing setup.
