Configuration information migration method, setting method and device thereof

Abstract

The invention discloses a configuration information migration method, a setting method and a device thereof. The migration method includes: when a PE device detects that the connection between the virtual device and the PE device is disconnected, obtains the corresponding configuration information on the PE device. Configuration information of the virtual device; the PE device sends configuration information corresponding to the virtual device to other PE devices, and when the PE device receiving the configuration information determines that the virtual device is migrated to an access device connected to itself, the The configuration information corresponding to the virtual device is set on itself. In the embodiment of the present invention, the configuration workload can be reduced, and the configuration process is simple.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for migrating configuration information in a large two-layer network, a setting method and a device thereof. Background technique [0002] Data center virtualization technology requires a large-scale layer-2 network technology. Large-scale layer-2 network technology allows virtual devices to migrate between access servers. Access servers may not be physically at the same location, and different access servers They are connected through a large layer 2 network, and the virtual device in one access server can be migrated to another access server due to some reasons (such as insufficient access server resources, etc.). [0003] VPLS (Virtual Private Lan Service, virtual private local area network service) is a kind of large two-layer network technology, such as figure 1 As shown in , it is a schematic diagram of an application scenario of VPLS in a data center.

Problems solved by technology

[0005] In the prior art, when a virtual device in one access server is migrated to another access server, it is necessary to reconfigure the QoS policy of the virtual device on the PE device connected to the other access server, that is, manually reconfigure the QoS policy of the virtual device on the PE device. Configuring QoS policy, the configuration workload is heavy, and the configuration is cumbersome

For example, when virtual device 3 is migrated to access server 2, the QoS policy for the MAC address of virtual device 3 needs to be manually reconfigured on PE device 3. The configuration workload is heavy and the configuration is cumbersome.
