Configuration procedure
You must configure the DHCPv6 server before configuring the DHCPv6 client. For information about
configuring the DHCPv6 server, see "Configuring the DHCPv6 server."
# Configure an IPv6 address for GigabitEthernet 2/0/1 that connects to the DHCPv6 server.
<Router> system-view
[Router] interface gigabitethernet 2/0/1
[Router-GigabitEthernet2/0/1] ipv6 address 1::2/48
# Configure GigabitEthernet 2/0/1 to use DHCPv6 for IPv6 address and prefix acquisition. Specify
IDs for the dynamic IPv6 prefix and dynamic DHCPv6 option group, and configure the client to
support rapid address and prefix assignment.
[Router-GigabitEthernet2/0/1] ipv6 dhcp client stateful prefix 1 rapid-commit
option-group 1
[Router-GigabitEthernet2/0/1] quit
Verifying the configuration
# Display DHCPv6 client information. The output shows that the DHCPv6 client has obtained an IPv6
address, an IPv6 prefix, and other configuration parameters from the DHCPv6 server.
