no – This command sets prefix configuration to default values.
The router advertises its global IPv6 pref ixes in its rout er advertise ments (RA s). An RA only in clud es the
prefixes of the IPv6 addresses configured on the interface whe re the RA is transmitted. Addresses are
configured using the ipv6 address interface configuration command. Each prefix advertisement inclu des
information about the prefix, such as its lifetime values and whether hosts should use the prefix for on -link
determination or addres s auto-configuration. Use the ipv6 nd prefix command to configure these values.
The ipv6 nd prefix command allows you to preconfigure RA prefix values before you configure the
associated interface addre ss. In order for the prefix to be included in RAs, you must configure an address
that matches the prefix using the ipv6 address command. Prefixes spe cified u sing ipv6 nd prefix without
associated interface addre ss will not be included in RAs and will not be committed to the device
configuration.
