Abstract

The present application provides an address backup method and device, which can enable a first DHCP client configured in a standby state to receive a second DHCP client configured in an active state corresponding to the first DHCP client by a DHCP server When sending the response message of the address request message, obtain the address information in the response message; and record the address information locally, so that the locally recorded address information and the second DHCP client The recorded address information is the same. This application enables the DHCP client in the standby state to directly obtain the same address information recorded by the DHCP server in the active state from the response message fed back by the DHCP server, thereby avoiding the DHCP client in the active state from transmitting addresses through the channel information, thereby reducing the occupation of channel bandwidth and improving synchronization efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to an address backup method and device. Background technique [0002] As customers have higher and higher requirements for the security performance of network equipment, it is inevitable to use a dual-system hot backup environment for networking deployment in many occasions. Since most DHCP clients access the network by dynamically assigning IP addresses through DHCP (DynamicHostConfigurationProtocol), in order to achieve dual-system hot backup for DHCP clients, in addition to The static configuration is backed up, and the dynamic configuration of the DHCP client needs to be synchronized. For example, the address information dynamically allocated by the DHCP server to the DHCP client also needs to be played synchronously. However, for the synchronization of the above address information, at present, it can only rely on the channel between the active and stan...
