The read module of step 102, configuration response end receives the IPv6 message from main frame, reads the content of the IPv6CP config option in the IPv6 message.
The processing module of step 103, configuration response end generates back message using according to the content of received config option, and selected IPv6 network parameter is placed the config option respective field of back message using.
Here, be with selected IPv6 Address, the config option respective field that network parameter values such as Primary DNS Address, Secondary DNSAddress place back message using.At inserting described respective field, owing to carry config option in the configuration request message that the configuring request end sends, and in the config option, may comprise the field of corresponding IPv6 Address, network parameters such as Primary DNS Address, Secondary DNSAddress respectively; When the configuration response end responds, back message using is also to carry config option in the response message, may comprise the field of network parameters such as corresponding IPv6 Address, Primary DNS Address, Secondary DNS Address respectively equally, so, when inserting concrete network parameter values, need insert the respective field in the config option, such as, the parameter value of this network parameter of IPv6 Address is inserted in the config option and the corresponding field of IPv6 Address.
The back message using that the sending module of step 104, configuration response end generates processing module sends to the main frame of opposite end, as the response to received IPv6CP message.
Step 105, main frame are carried out operations such as network configuration according to the IPv6 network parameter in the back message using that is obtained.
Here, main frame is according to IPv6 Address, the network parameter values such as Primary DNS Address, SecondaryDNS Address obtained, carries out concrete operations such as network configuration.
As shown in Figure 7, in the present embodiment, the negotiations process of PPP config option may further comprise the steps:
Here, configuration request message realizes that by the IPv6CP message IPv6CP config option that carries in the IPv6CP message is IPv6-Prefix, config options such as Primary DNS Address, Secondary DNS Address.At this moment, the content of config options such as IPv6 Address, Primary DNS Address, Secondary DNS Address can not comprise concrete parameter value, is sky, inserts concrete parameter value after the response of receiving the configuration response end again.
The read module of step 202, configuration response end receives the IPv6 message from home gateway, reads the content of the IPv6CP config option in the IPv6 message.
The processing module of step 203, configuration response end generates back message using according to the content of received config option, and selected IPv6 network parameter is placed the config option respective field of back message using.
Here, be with selected IPv6-Prefix, the config option respective field that network parameter values such as Primary DNS Address, Secondary DNSAddress place back message using.
The back message using that the sending module of step 204, configuration response end generates processing module sends to the home gateway of opposite end, as the response to received IPv6CP message.
Here, home gateway is according to network parameter values such as the IPv6-Prefix, the Primary DNS Address that are obtained, Secondary DNS Address, carries out concrete operations such as network configuration.
Need to prove, can in computer system, carry out in the step shown in the flow chart of accompanying drawing such as a set of computer-executable instructions, and, though there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
Here, the config option that more than relates to is represented with confguration-option; Main frame is represented with Host; Home gateway is represented with Residential Gateway.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
