takes effect. For automatic generation of an IPv6 link-local address, see the ipv6 address auto
link-local command.

Parameters
prefix-number: Specifies an IPv6 prefix by its ID in the range of 1 to 1024. The specified IPv6 prefix
can be manually configured or obtained through DHCPv6.
sub-prefix: Specifies the sub-prefix bit and host bit for the IPv6 global unicast address.
prefix-length: Specifies the sub-prefix length in the range of 1 to 128.
Usage guidelines
This command enables an interface to automatically generate an IPv6 global unicast address based
on the specified IPv6 prefix, sub-prefix bit, and host bit.
An interface can generate only one IPv6 global unicast address based on the prefix specified by
using the ipv6 address command. To configure the interface to generate a new IPv6 address,
execute the undo ipv6 address command to delete the configuration, and then execute the ipv6
address command.
Examples
# Configure a static IPv6 prefix AAAA::/16 and assign ID 1 to the prefix. Configure VLAN-interface
100 to use this prefix to generate the IPv6 address AAAA:CCCC:DDDD::10/32 and advertise this
prefix.
