DHCPv6 Client Functionality
DHCPv6 Clients can request the delegation of prefixes from a DHCPv6 Server. The IPv6
prefixes acquired from a delegating DHCPv6 Server are stored in an IPv6 prefix pool. The
prefixes in the IPv6 prefix pool can be used to number downstream device interfaces.
A DHCPv6 Client is enabled on an individual IPv6-enabled VLAN interface, and can also
request and accept those configuration parameters that do not require a DHCPv6 Server
to maintain any dynamic state for individual clients, such as DNS server addresses.
DHCPv6 Server Selection by a DHCPv6 Client
A DHCPv6 Client builds a list of DHCPv6 servers by sending a solicit message and by
receiving advertisement replies from DHCPv6 Servers. The replies are ranked by the
DHCPv6 Client based on preference value, when DHCPv6 Servers add a preference value
to their advertisement messages.
See the section
for the sequence of messages sent and received
between DHCPv6 Servers and DHCPv6 Clients and brief descriptions of the messages.
For the syntaxes, parameters, descriptions, defaults, and examples for all of the commands
used in the following DHCPv6 configurations, refer to
for the DHCPv6 Client commands.
Note
The IPv6 addresses shown use the address space 2001:0db8::/32, defined in RFC
3849 for documentation purposes. These addresses should not be used for
practical networks (other than for testing purposes) nor should they appear on
any public network.
