Abstract

The present invention provides a hot backup method and device for a DHCPv6 server, comprising: the main DHCPv6 server receives a service request containing a VDUID sent by a DHCPv6 client, and determines whether the stored DUID linked list contains the VDUID, and if so, it is a DHCPv6 client Provide business services; the active DHCPv6 server notifies the standby DHCPv6 server when a fault occurs, the standby DHCPv6 server will switch the VDUID status from unavailable to available and provide business services for DHCPv6 clients, and when the standby DHCPv6 server restarts, the standby DHCPv6 server will The DHCPv6 server can generate the same VDUID as the active DHCPv6 server, thereby improving the timeliness and reliability of the standby DHCPv6 server taking over the active DHCPv6 server when the active DHCPv6 server fails.

Description

technical field [0001] The invention relates to communication technology, in particular to a hot backup method and device for a DHCPv6 server. Background technique [0002] Internet Protocol Version 6 (IPv6 for short) Dynamic Host Configuration Protocol for IPv6 (DHCPv6 for short) server can assign IPv6 addresses, prefixes and network configuration parameters to network nodes. The DHCPv6 server assigns addresses, prefixes, and network configuration parameters to the DHCPv6 client by responding to the request from the DHCPv6 client. If the DHCPv6 client and the DHCPv6 server are not in the same subnet, the DHCPv6 relay can forward the packets sent by the DHCPv6 client and the DHCPv6 server. To realize cross-segment service requests, thereby reducing the burden on network administrators and improving the manageability of address allocation. [0003] DHCPv6 defines a DHCP Unique Identifier (DHCP Unique Identifier, DUID for short) as an identifier of a DHCPv6 server and a DHCPv...
