18. DHCP Client-Initiated Configuration Exchange
18.1. Client Behavior
18.1.8. Receipt of Reply Messages
Upon the receipt of a valid Reply message in response to a Solicit
(with a Rapid Commit option), Request, Confirm, Renew, Rebind or
Information-request message, the client extracts the configuration
information contained in the Reply. The client MAY choose to report
any status code or message from the status code option in the Reply
message.
The client SHOULD perform duplicate address detection [21] on each
of the addresses in any IAs it receives in the Reply message before
using that address for traffic. If any of the addresses are found
to be in use on the link, the client sends a Decline message to the
server as described in section 18.1.7.
If the Reply was received in response to a Solicit (with a Rapid
Commit option), Request, Renew or Rebind message, the client updates
the information it has recorded about IAs from the IA options
contained in the Reply message:
- Record T1 and T2 times
- Add any new addresses in the IA option to the IA as recorded by
the client
- Update lifetimes for any addresses in the IA option that the
client already has recorded in the IA
- Discard any addresses from the IA as recorded by the client that
have a valid lifetime of 0 in the IA Address option
Management of the specific configuration information is detailed in
the definition of each option, in section 22.
If the client receives a Reply message with a Status Code containing
UnspecFail, the server is indicating that it was unable to process
the message due to an unspecified failure condition. If the client
retransmits the original message to the same server to retry the
desired operation, the client MUST limit the rate at which it
retransmits the message and limit the duration of the time during
which it retransmits the message.
When the client receives a Reply message with a Status Code option
with value UseMulticast, the client records the receipt of the
message and sends subsequent messages to the server through the
interface on which the message was received using multicast. The
client resends the original message using multicast.
When the client receives a NotOnLink status from the server in
response to a Confirm message, the client performs DHCP server
solicitation as described in section 17 and client-initiated
configuration as described in section 18. If the client receives any
Reply messages that do not indicate a NotOnLink status, the client
can use the addresses in the IA and ignore any messages that do
indicate a NotOnLink status.
When the client receives a NotOnLink status from the server in
response to a Request, the client can either re-issue the Request
without specifying any addresses or restart the DHCP server discovery
process (see section 17).
When the client receives a NoAddrsAvail status from the server in
response to a Request, the client can either try another server
(perhaps restarting the DHCP server discovery process) or use the
Information-Request to obtain configuration parameters only.
When the client receives a NoBinding status in an IA from the server
in response to a Renew message or a Rebind message, the client sends
a Request to reestablish an IA with the server.
When the client receives a valid Reply message in response to a
Release message, the client considers the Release event completed,
regardless of the Status Code option(s) returned by the server.
When the client receives a valid Reply message in response to a
Decline message, the client considers the Decline event completed,
regardless of the Status Code option(s) returned by the server.
24.4. Status Codes
IANA is requested to record the status codes defined in the following
table. IANA is requested to manage the definition of additional
status codes in the future.
