Operation
Figure 54 Operation of stateless DHCPv6
As shown in Figure 54 , stateless DHCPv6 operates in the following steps.
1. The DHCPv6 client multicasts an Information-request message to the multicast address of all
DHCPv6 servers and DHCPv6 relay agents. The Information-request message contains an Option
Request option, specifying the configuration parameters that the client requests from the DHCPv6
server.
2. After receiving the Information-request message, the DHCPv6 server returns the client a Reply
message containing the requested configuration parameters.
3. The client checks the Reply message. If the obtained configuration parameters match those
requested in the Information-request message, the client performs network configuration with the
parameters. If not, the client ignores the configuration parameters. If multiple replies are received,
the first received reply will be used.
