Embodiment Construction

[0046] The network planning method for saving IPV4 addresses by configuring static routes proposed by the present invention requires equipment for address planning, and a router is taken as an example here. There is at least one Ethernet interface on the router, and the router is interconnected with other devices through the Ethernet interface. The general networking is shown in Figure 1. In this embodiment, there are four Ethernet interfaces 111, 112, 113, and 114. The address planning router 110 The uplink router 120 is interconnected through the Ethernet interface 111, and the following devices are also interconnected through the Ethernet interfaces 112, 113, 114. The devices 133, 134 can be directly connected, and the devices 131, 132 can also be interconnected through the layer 2 device 130.

[0047] In order to ensure that device 131, device 132, device 133, and device 134 in Figure 1 are configured with the same network segment address and the same gateway address, they ...

Abstract

The invention discloses a network device that can save address resource. It includes: ether interface module that contains internal ether interface and external interface, configuration management module, message transmission module, static direct-access route module and address resolution protocol response module. The configuration management module connects to the static direct-access route module and ARP response module; the static direct-access route module and ARP response module connects to the ether interface module by the message transmission module; and the external ether interface of the ether interface module connects to public network device; the internal ether network connects to the inter-connecting device. The invention also provides a address resource saving network device and address layout method. It avoids address wasting caused by configuring interface address and the influence to the system performance when the real-time accession executed by host computer route. The software cost increased is not much, and more important, the transmission performance of route device is not influenced.

Description

technical field [0001] The invention relates to an interface address planning method for network equipment such as routers and routing switches, in particular to a network equipment and an address planning method for saving IPV4 address resources. Background technique [0002] In the prior art, when planning a network address for a routing device, a method of subnetting is mainly used, and an interface address is configured for each interface to divide a subnet. When some routing devices are networked, multiple Ethernet interfaces can be bundled into one virtual interface, and an interface address is configured on this virtual interface, so that multiple Ethernet interfaces share one IPV4 (Internet Protocol Version 4) interface address. In addition, at present, NAT (Network Address Translator) can be used to solve the shortage of IPV4 addresses. Access users use private network addresses, and there is no need to consider the shortage of IPV4 addresses for access users. In g...
