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.

# Configure VLAN-interface 10 to obtain an IPv6 prefix through DHCPv6 and assign ID 2 to the
obtained prefix. Configure VLAN-interface 100 to use the obtained prefix to generate the IPv6
