Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
Router is hung under use without user's manual configuration in order to realize, the embodiment of the present application provides one
The method of kind configuration router can first close the dynamic host configuration protocol (Dynamic of router in router startup
Host Configuration Protocol, DHCP) server capability, and then if it is determined that router be lower extension router, then may be used
It is line relay mode by configuration of routers.As it can be seen that in this way, router can judge automatically whether itself is lower extension routing
Device then itself will be configured to line relay mode automatically if lower extension router, i.e., lower router of hanging only has relay function,
Without routing function, the coverage area of wireless signal can be expanded in this way, egress router and the routing of lower extension will not occur
The problem of LAN mouth of device can not be surfed the Internet using terminal caused by identical address network segment by lower extension router is being not necessarily to user
The lower configuration for hanging router is completed in the case where manual configuration.
Method provided by the embodiments of the present application is applied in communication system as shown in Figure 2, in the system includes one and goes out

In schematically illustrate and hang router under three, these three are lower to hang routers can be connected to egress router different
LAN mouthfuls.
Optionally, lower extension router can also use cascade mode, for example, the lower LAN mouth for hanging router 4 is connected to down
Hang the WAN mouth of router 1.
The method of configuration router provided by the embodiments of the present application is specifically addressed below.
It should be noted that router involved in the embodiment of the present application, egress router and lower extension router are nothing
Line router, each message name and each parameter name in the embodiment of the present application are only as an example, can also be in specific implementation
For other titles, it is described collectively herein.
Communication system as shown in connection with fig. 2, the embodiment of the present application provides a kind of method for configuring router, such as Fig. 3 institute
Show, this method comprises:
When S301, router startup, the dhcp server functionality of router is closed.
Wherein, the LAN mouth of router generally has the function of Dynamic Host Configuration Protocol server (server) that is, router can pass through LAN mouthfuls
IP address is distributed for client.It is not determined after router startup in the case where itself whether being lower extension router, first by itself
Dhcp server functionality keep in off position, if the dhcp server functionality of router is not opened, maintain DHCP service
The closed state of device closes the dhcp server functionality of router if the DHCP function of router has turned on.
It is line relay mode by configuration of routers if S302, router are lower extension router.
Wherein, line relay mode refers to, which only provides relay function, does not provide routing function, at this time
The lower extension router can be regarded as an interchanger, the lower extension router is in subsequent use process, LAN mouthfuls of Dynamic Host Configuration Protocol server
Function remains off.
It is also understood that terminal can access network, but the IP used when accessing terminal to network by lower extension router
Address is that egress router provides.Specifically, lower extension router can incite somebody to action after terminal issues DHCP discover message
DHCP discover message is forwarded to egress router, and then egress router will carry IP address for terminal distribution
DHCP offer message is sent to lower extension router, then the DHCP offer message is sent to terminal by lower extension router, into
And terminal can be surfed the Internet by lower extension router, but practical lower router of hanging only provides line relay, there is no as DHCP
Sever is terminal distribution IP address.
Using the method for configuration router provided by the embodiments of the present application, router can close the Dynamic Host Configuration Protocol server function of itself
Can, and judge automatically whether itself is lower extension router, if lower extension router, then it itself will be configured to line relay mould automatically
Formula, i.e., lower router of hanging only have relay function, do not have routing function, can expand the coverage area of wireless signal in this way,
Egress router will not occur and the lower LAN mouth for hanging router can not be under using terminal caused by identical address network segment
The problem of hanging router online completes the lower configuration for hanging router in the case where being not necessarily to user's manual configuration.
Further, since lower extension router is configured as line relay mode, do not have routing function, so under terminal passes through
Hang router online when, will not lower extensions router progress network address translation (Network Address Translation,
NAT), speed of surfing the Internet will not be reduced terminal accesses network by lower extension router.If also, lower extension router has road
By function, then the LAN mouth of the lower LAN mouth for hanging router and egress router uses different address network segments, if two terminals point
Not Tong Guo lower extension router and egress router online, the two terminals cannot be used cooperatively, for example, if terminal computer passes through
Lower extension router accesses network, and projector accesses network by egress router, if computer need to pass through the side of wireless communication
Display interface is passed through projector by formula, but computer and projector are surfed the Internet by different network segments, and projector just can not be to electricity
The display interface of brain is projected, but uses embodiments herein, and lower extension router does not provide routing function, only provides relaying
Function, so the same local area network is still used by lower extension router and by the terminal that egress router accesses network, it will not
There is the problem of cannot being used cooperatively.
It is understood that above-mentioned router may be lower extension router, it is also possible to be egress router, the application is implemented
Example has different processing methods to lower extension router and egress router, this is based on, to configuration in another embodiment of the application
The method of router is described in detail, as shown in figure 4, this method comprises:
When S401, router startup, the dynamic host configuration protocol DHCP server capability of router is closed.
S402, judge whether the automatic line relay function of router is in the open state.
The configuration information about automatic line relay function of itself storage can be read in router, is sentenced according to the configuration information
Whether automatic line relay function of breaking is in the open state.
If so, executing S403；If it is not, illustrating that the router can not be used as lower extension router, it is believed that the router is
Egress router then executes S405.
S403, judge whether router is lower extension router.
If so, executing S404；If it is not, then executing S405.
It should be noted that can star a timer while starting the judgment step of S403, if timer is super
When, do not judge whether router is lower extension router, then terminates to judge process yet, it is believed that the router is not lower extension routing
Device executes S405.
It is line relay mode by configuration of routers if S404, router are lower extension router.
In one implementation, if the WAN mouth of router and LAN mouthfuls are not in the same exchanger core on piece, by WAN
Mouth and LAN mouthfuls of bridgings create a bridge, then WAN mouthfuls and LAN mouthfuls are added on this bridge, to realize WAN mouthfuls and LAN
The bridging of mouth.Then WAN mouthfuls of the information for realizing routing function is deleted, wherein for realizing the packet of routing function
Include routing rule, safety regulation, service quality (Quality of Service, QoS) information, firewall information etc..
In another implementation, if the WAN mouth of router and LAN mouthful are in the same exchanger core on piece, due to friendship
LAN and WAN in changing planes can be generally isolated by VLAN, and the routing function of the router is closed in the embodiment of the present application
Can, and wired repeater mode is set by the router, exchanger core on piece can be deleted about WAN mouthfuls of virtual LAN
(Virtual Local Area Network, VLAN) configuration information, then by WAN mouthfuls be added to LAN mouthfuls belonging in VLAN,
And the WAN mouthfuls of information for realizing routing function is deleted, belonging between same WAN mouthfuls and LAN mouthful so directly to transmit
Data, without carrying out NAT conversion.
S405, the dhcp server functionality for opening router.
Wherein, if the router is egress router, the dhcp server functionality and router of router are opened
Nat feature, the egress router carry out normal online dialing process.
Using method provided by the embodiments of the present application, when router startup, it can judge automatically whether itself is the road Xia Gua
Line relay mode then itself will be configured to if lower extension router by device, if not lower extension router, then open itself
Dhcp server functionality, to realize the function of egress router, it is seen that automatically configuring for router may be implemented using this method.
Since lower extension router is configured as line relay mode, do not have routing function, so terminal is surfed the Internet by lower extension router
When, NAT conversion will not be carried out in lower extension router, upper network speed will not be reduced terminal accesses network by lower extension router
Rate.
In addition, if lower extension router has routing function, the LAN mouth of lower the LAN mouth for hanging router and egress router
Using different address network segments, if two terminals pass through lower extension router and egress router online respectively, the two terminals will
It cannot be used cooperatively, for example, projector accesses net by egress router if terminal computer accesses network by lower extension router
Network, if display interface need to be passed through projector by way of wireless communication by computer, but computer and projector pass through
Different network segment online, projector can not just project the display interface of computer, but use embodiments herein, lower extension
Router does not provide routing function, only provides relay function, so accessing net by lower extension router and by egress router
The terminal of network still uses the same local area network, is not in the problem of cannot being used cooperatively.
Below to above-mentioned S403, judge router whether be it is lower hang router method be described in detail, such as Fig. 5 institute
Show, this method comprises:
S501, router obtain the first IP address by WAN mouthfuls of dhcp client (client) function.
Specifically, router can be used as DHCP client for WAN mouthfuls, by DHCP protocol to upstream gateway application first
IP address.
S502, judge whether the first IP address is public network IP address.
Wherein, lan address generally comprises three address network segments, is respectively as follows: 10.0.0.0-10.255.255.255；
172.16.0.0-172.31.255.255；192.168.0.0-192.168.255.255.If the first IP address belong to this three
Any one in a address network segment, it is determined that the first IP address is LAN IP address；If the first IP address is not belonging to above-mentioned
Three address network segments, it is determined that the first IP address is public network IP address.
If so, executing S503；If it is not, then executing S504.
S503, to determine router not be lower extension router.
If router is not lower extension router, illustrate that the router is egress router, then the outlet router continues
Realize normal router feature.
It S504, is the salty newly-generated MAC Address of WAN.
S505, router obtain the second IP address by WAN mouthfuls of dhcp client function according to MAC Address.
Router will WAN mouthfuls be used as dhcp client, new MAC Address is disguised oneself as WAN mouthfuls of MAC Address, is passed through
DHCP protocol is to the second IP address of upstream gateway application.
S506, router judge whether to get the second IP address.
If so, executing S507；If it is not, then executing S503.
If router, which has not been obtained, illustrates that upstream gateway limits the IP address distribution of the router to the second IP address
System, i.e., the router can only obtain an IP address, IP address that cannot be new by new MAC Address application, and upstream gateway is
Carrier gateway, the router are egress router, which can not carry out line relay.
Conversely, illustrating that upstream gateway does not distribute the IP address of the router if router gets the second IP address
It is limited, which can apply for multiple IP address, so the upstream gateway of the router is not carrier gateway, the road
Have the condition for carrying out line relay by device, and then can determine that the router is lower extension router.
S507, determine that router is lower extension router.
As it can be seen that can be judged automatically using method provided by the embodiments of the present application, after router startup itself whether be under
Router is hung, and then itself can be matched according to the lower configuration rule for hanging router automatically if itself is lower extension router
