DHCP Client

– 914 –

When the DHCP client process is enabled and a prefix is successfully

acquired, the prefix is stored in the IPv6 general prefix pool. Other

commands and applications (such as the

ipv6 address

command) can

then refer to the prefixes in the general prefix pool.

DHCPv6 clients can also request configuration parameters that do not

require a server to maintain any dynamic state for individual clients,

such as DNS server addresses.

DHCPv6 clients builds a list of servers by sending a solicit message and

collecting advertised message replies. These servers are then ranked

based on their advertised preference value. If the client needs to

acquire prefixes from servers, only servers that have advertised
prefixes are considered.

DHCPv6 clients and servers are identified by a DHCP Unique Identifier

(DUID) included in the client identifier and server identifier options. Static

or dynamic address prefixes may be assigned by a DHCPv6 server based

on the client’s DUID.
