Technical field
The present embodiments relate to the communications field, and more particularly, to the method for one assignment of the Internet protocol in the field of communications (InternetProtocol, IP) address, router and system.
Background technology
Expansion along with the development of network and scale thereof, generally use DHCP (DynamicHostConfigurationProtocol, DHCP) carry out management ip address, so that assigned IP addresses dy and configuration parameter, so that the user on network can apply for that IP address is without any network parameter of manual configuration automatically.
At present, the support of router complete machine creates and must configure default gateway (defaultgateway) (also referred to as default gateway) under 4K address pool (addresspool) and address pool.After configuration default gateway, gateway route (i.e. Host routes) of corresponding network segment route and 32 will be issued immediately.The IP address of user have to default gateway address at the same network segment, and on same equipment, the gateway in different address pond does not allow identical, or the network segment in different address pond does not allow overlap.
Existing IPOE (IPoverEthernet) and PPPOE (PointtoPointOverEthernet, the point-to-point protocol on Ethernet) user obtains IP address from the address pool of router.For IPOE user, default gateway must be in the same network segment with the IP address of user, to ensure the ARP (AddressResolutionProtocol that router timing can be sent by user, address resolution protocol) probe messages (message) gives a response, and otherwise router will be considered to user and rolled off the production line thus discharging IP address.
But, for PPPOE user, owing to it is point-to-point communication, so user need not judge default gateway whether with the IP address of oneself at the same network segment, but the address distribution of current PPPOE user is but the same with IPOE, namely the IP address that default gateway and user obtain at the same network segment and does not allow default gateway address is distributed to user, and this certainly will cause PPPOE user's address unnecessary waste.
Summary of the invention
The embodiment of the present invention provides a kind of method of IP address of distribution in the field of communications, router and system, it is possible to save IP address for user.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
In the following description, for PPPOE, the embodiment of the present invention is described, but, it will be appreciated by those skilled in the art that the embodiment of the present invention is not limited to this, it is also possible to the embodiment of the present invention is applied to other point-to-point schemes.
Below, the embodiment of the present invention will be described in detail with reference to the accompanying drawing figures.
Fig. 1 illustrates the example of a concrete IP address.As shown in fig. 1, " 10.110.98.195 " is allocated to the IP address of PPPOE user, and " 255.255.254.0 " is subnet mask (B class), and " 10.110.98.1 " is default gateway, takies an IP address.
In order to distribute IP address to user, first address pool (addresspool) is created on the router, under address pool, configure default gateway (DefaultGateway) (or being called default gateway) and specify the length of subnet mask, then configuration subnet section (section), it is desirable to subnet section belongs to the network segment scope in this address pool that default gateway limits.The IP address of user obtains just in the scope of subnet section.Under normal circumstances, a router support creates 4k address pool, the corresponding network segment (segment) of each address pool, and can include 8 sub-network segments under the network segment of an address pool.
Owing to PPPOE is point to point link, as long as the router of correspondence can be found according to the IP address of gateway, thus user without judge gateway whether with the IP address of oneself whether in the same network segment.Therefore, the embodiment of the present invention, except configuration default gateway and subnet mask, is provided with and uses gateway (borrowedgateway).Default gateway, is in esse router, naturally takies an IP address.Use gateway, namely use the IP address of local loopback loopback mouth or other physical interfaces as gateway, distribute to user such that it is able to save out by default gateway.
Fig. 2 illustrates the flow chart of the exemplary method 20 for distributing IP address for PPPOE user according to embodiments of the present invention.
As shown in Figure 2, in the 201 of method 20, configuration is used gateway and issues this gateway using gateway route to described PPPOE user.Wherein, this gateway route can be the Host routes of the IP address of configuration under native interface.Here, the process of gateway is used in configuration can be find such as local loopback (loopback) interface, gigabit Ethernet (GigabitEthernet) interface or link aggregation (Eth-Trunk) interface and determine the process of its IP address.
In 202, configuration default gateway and subnet mask determine the network segment belonging to PPPOE user.As is known to the person skilled in the art, it is possible to determine the network segment belonging to PPPOE user by the IP address of default gateway and subnet mask are carried out logical AND (AND) computing.Additionally, according to embodiments of the present invention, the default gateway configured can must be no longer an in esse router.
In 203, configure the subnet section under the described network segment, to distribute to described PPPOE user.For example, it is possible to the quantity according to the IP address needed for described PPPOE user distributes subnet section.
According to embodiments of the present invention, except configuration default gateway, also additional configuration uses gateway, and the gateway route of gateway route rather than the default gateway using gateway is issued to PPPOE user, therefore PPPOE user can utilize this to use gateway as gateway, such that it is able to save out by the IP address of default gateway.
According to embodiments of the present invention, as long as use the IP address that the IP address that gateway uses is the arbitrary physical interface configuration existed on the router, and open (undoshutdown) with the state of this interface or closedown (shutdown) is unrelated.It is to say, not the on/off state of interface tube how, as long as it is the interface existed on the router and has been configured with IP address for it, then this IP address can serve as the IP address using gateway and uses.The on/off state of interface does not affect forwarding, without bringing other costs.Preferably, it is possible to use one in loopback interface, GigabitEthernet interface and Eth-Trunk is used as using gateway.Can select to use in loopback interface, GigabitEthernet interface and Eth-Trunk by user's manual configuration which be used as using gateway.
After being configured with and using gateway, issue the gateway route using gateway configured to PPPOE user, enable a user to that this is used gateway and use as gateway.In addition, configuration default gateway and subnet mask only for purpose of determine this address pool the network segment, namely can to user distribution IP address subnet section belonging to scope, to belong to the same network segment to the IP address of user's distribution and default gateway, but no longer issue 32 gateways route (i.e. Host routes) of default gateway to user.
Therefore, user's use can also be distributed in the IP address of default gateway.
Fig. 3 (a) and Fig. 3 (b) illustrates the comparison of the example of the order for distributing IP address according to embodiments of the present invention and the example of the order of prior art.Wherein, Fig. 3 (a) illustrates the command format of method according to embodiments of the present invention, and Fig. 3 (b) illustrates the command format of prior art.
In Fig. 3 (a), first gateway is used in configuration, it is assumed that utilize lookback interface as using gateway.Then, configuration default gateway be " 100.0.0.200 ", and specify subnet mask length be 24 (namely, it is intended that subnet mask is 255.255.255.0).Subnet mask can be configured according to the number of host etc. in the number of subnet or each subnet.But, those skilled in the art it is apparent that, it is also possible to use the method that any other is suitable to determine subnet mask.Configuration default gateway and subnet mask be " 100.0.0.20024 " only for purpose of determine will to user distribute IP address belonging to the network segment.
Then, configuring subnet section according to this default gateway is " 100.0.0.100100.0.0.255 ".Here, according to embodiments of the present invention, owing to not issuing the gateway route of default gateway to PPPOE user but only issuing the gateway route using gateway to user, so " 100.0.0.200 " as the IP address of default gateway can also be assigned to PPPOE user's use.
By contrast, referring to Fig. 3 (b), in the prior art, namely when do not configure use gateway and only configure default gateway, gateway route as default gateway is distributed to user, so its IP address " 101.0.0.1 " cannot be assigned to user and use.
Therefore, according to embodiments of the present invention, when router complete machine can support to create 4K address pool, it is not necessarily each address pool and creates an independent gateway, can be that every router saves 4K IP address for distributing to PPPOE user's use for this, it is possible to effectively help operator to improve income.
Fig. 4 illustrates the block diagram of the demonstrative structure 40 of the router for distributing IP address for PPPOE user according to embodiments of the present invention.
As shown in Figure 4, router 40 can include IP address distributor 401.This IP address distributor 401 is used gateway for configuring and issues this gateway using gateway route to described PPPOE user, configuration default gateway and subnet mask determine the network segment belonging to PPPOE user, and configure the subnet section under the described network segment, to distribute to described PPPOE user.
According to embodiments of the present invention, except configuration default gateway, also additional configuration uses gateway, and the gateway route of gateway route rather than the default gateway using gateway is issued to PPPOE user, therefore PPPOE user can utilize this to use gateway as gateway, such that it is able to save out by the IP address of default gateway.
Additionally, the IP address using gateway configured by described IP address distributor 401 can be the IP address of the either interface configuration for existing on the router.Preferably, described either interface can be in local loopback loopback interface, GigabitEthernet interface and Eth-Trunk.
Additionally, the subnet section including the IP address of described default gateway can be distributed to described PPPOE user by described IP address distributor 401.
