Configuring the DHCPv6 server
Overview
To simplify IPv6 address management and network configuration, you can configure a DHCPv6 server
to assign IPv6 addresses, IPv6 prefixes, and other configuration parameters to DHCPv6 clients.

DHCPv6 address pool
A DHCPv6 address pool includes IPv6 addresses, IPv6 prefixes, and other configuration parameters that
the DHCPv6 server assigns to DHCPv6 clients.
A DHCPv6 address pool can include the following items:
• Static IPv6 prefix—Statically bound to a DHCPv6 client and can only be assigned to that client.
• Prefix pool with a prefix range—The DHCPv6 server dynamically assigns an IPv6 prefix from the
prefix pool to a DHCPv6 client.
• Static IPv6 address—Statically bound to a DHCPv6 client and can only be assigned to that client.
• IPv6 subnet—The DHCPv6 server dynamically assigns an IPv6 address on the subnet to a DHCPv6
client.
• DNS server address
• DHCPv6 client domain name
• SIP server address or domain name
• Address Family Transition Router (AFTR) address
Prefix selection process
To configure a DHCPv6 server to assign IPv6 prefixes to DHCPv6 clients, you must apply an address pool
on the receiving interface of the DHCPv6 server. Upon receiving a request, the DHCPv6 server searches
all the address pools for a static IPv6 prefix bound to the client.
