2. If the receiving interface has an address pool, the DHCP server selects an IPv6 address or prefix
and other configuration parameters from this address pool.
3. If there is no static address pool and the receiving interface has no address pool, the DHCPv6
server selects an address pool in the following way:
{ If the client and the server reside on the same subnet, the DHCP server matches the IPv6 address
of the receiving interface against the subnets of all address pools, and selects the address pool
with the longest-matching subnet.
{ If the client and the server reside on different subnets (a DHCPv6 relay agent is in-between), the
DHCPv6 server matches the IPv6 address of the DHCPv6 relay agent interface closest to the
client against the subnets of all address pools, and selects the address pool with the
longest-matching subnet.
Configuration prerequisites
Before you configure the DHCPv6 server, enable IPv6 by using the ipv6 command. For more information
about the ipv6 command, see Network Management Command Reference.

Configuring IPv6 prefix assignment
Use one of the following methods to configure IPv6 prefix assignment:
• Configure a static IPv6 prefix binding in an address pool—If you bind a DUID and an IAID to an
IPv6 prefix, the DUID and IAID in a request must match those in the binding before the DHCPv6
server can assign the IPv6 prefix to the DHCPv6 client. If you only bind a DUID to an IPv6 prefix, the
DUID in the request must match the DUID in the binding before the DHCPv6 server can assign the
IPv6 prefix to the DHCPv6 client.
