Abstract: Embodiments of the present disclosure disclose a method and an apparatus for restoring a network device to factory defaults, and a network device, and relate to the field of configuration management technologies. A NETCONF server determines that the network device needs to be restored to the factory defaults; the NETCONF server replaces data in a startup configuration datastore and a running configuration datastore in the NETCONF server with factory defaults data in a factory defaults datastore, where the factory defaults datastore is dedicated to storing the factory defaults data of the network device. The NETCONF server delivers the data in the running configuration datastore after replacement to a plurality of service modules. Then, the plurality of service modules performs a validation operation based on the data delivered by the NETCONF server.

Abstract: The present invention provides a method for controlling generation of routing information, a method for generating routing information, and apparatuses thereof. When it is detected that a virtual machine is migrated out of or migrated into a data center, a subnet to which the virtual machine belongs is determined, a route control identifier for adjusting routing information of a virtual machine that belongs to the subnet and is in the data center is determined, and the route control identifier is sent to the data center, so that the data center adjusts, according to the route control identifier, routing information of the virtual machine that belongs to the subnet and is in the data center. In this way, generation of many host routes in data centers when a virtual machine is migrated across the data centers is prevented.

Abstract translation: 本发明提供了一种控制路由信息生成的方法，一种路由信息的生成方法及其装置。 当检测到虚拟机被迁移或迁移到数据中心时，确定虚拟机所属的子网，用于调整属于子网并且处于该子网中的虚拟机的路由信息​​的路由控制标识符 确定数据中心，并将路由控制标识符发送到数据中心，使得数据中心根据路由控制标识符，调整属于子网并处于数据中心的虚拟机的路由信息​​。 通过这种方式，可以防止在虚拟机跨数据中心迁移时在数据中心中生成许多主机路由。

Abstract: The present disclosure disclose a configuration management method and apparatus, and a device. A control device determines that an application message needs to be published to a target logical group. The control device obtains an identifier of the target logical group and queries, according to a gateway mapping table and the identifier of the target logical group, a gateway connected to each of the at least one target terminal, to obtain at least one target gateway. The control device generates based on the application message, a MQTT publish packet and sends the MQTT publish packet to the at least one target gateway, where the MQTT publish packet is used to instruct a target gateway that receives the MQTT publish packet to send a corresponding application message to each target terminal that is connected to the target gateway and that belongs to the target logical group.

Abstract: Embodiments of the present disclosure disclose a method and an apparatus for restoring a NETCONF server to factory defaults, and relate to the field of configuration management technologies. A NETCONF server receives a command for restoring to factory defaults sent by a NETCONF client, where the command for restoring to factory defaults is a remote procedure call (RPC) command that is based on a Yang model of the NETCONF for restoring the NETCONF server to the factory defaults. The NETCONF server replaces data in the running configuration datastore with factory defaults of the NETCONF server according to the command for restoring to factory defaults.
