Problems solved by technology

[0007] Since user equipment 1 and user equipment 2 are in different data centers (site networks), when the GVRP registration packet reaches the edge device ED in the data center, the edge device ED cannot send the VLAN registration information to the peer data center, causing user Data communication in VLAN 100 cannot be performed between device 1 and user device 2
[0008] In order to solve the above problems, VLAN configuration is usually pre-configured on the edge device ED of the site network. If there are user equipment belonging to this VLAN), you need to adopt the reserved VLAN method, that is, pre-configure these reserved VLANs on the EVI interface of the ED of the site network, such as VLAN100. However, this will cause If there is no user equipment in VLAN 100, the broadcast packets of VLAN 100 in other sites will still be flooded into the network of this site

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] In the embodiment of the present invention, in order to realize the dynamic VLAN attribute registration across data centers, for a site network that needs to support the dynamic VLAN attribute registration function across data centers, the dynamic VLAN attribute registration function can be pre-configured on the edge device of the site network. When the ED of the site network receives the VLAN attribute registration message from the site network, the VLAN attribute registration information carried in the VLAN attribute registration message is transferred from the ED corresponding to the remote site network configured with the dynamic VLAN attribute registration function. The outbound interface sends out, and finally reaches the ED...

Abstract

The invention provides a dynamic VLAN (Virtual Local Area Network) attribute registration method and device. According to the technical scheme, the method comprises the following steps: configuring a dynamic VLAN attribute registration function on an ED (Edge Device) of a current site; and after the ED receives a VLAN attribute registration message from a site network, transmitting VLAN attribute registration information in the VLAN attribute registration message to an ED of a remote site configured with the dynamic VLAN attribute registration function, regenerating a VLAN attribute registration message corresponding to the VLAN attribute registration information by using the ED of the remote site, and transmitting the regenerated VLAN attribute registration message in the remote site. Through adoption of the method and the device, cross-data-center dynamic VLAN attribute registration can be realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dynamic virtual local area network (VLAN) attribute registration method and device. Background technique [0002] Ethernet Virtualization Interconnection (Ethernet Virtualization Interconnection, EVI) is a "MAC (Media Access Control, Media Access Control) in IP" technology, used to implement L2VPN (Layer2Virtual Private Network) based on IP (Internet Protocol, Internet Protocol) core network Network, Layer 2 virtual private network). The EVI network consists of a core network, a site network, and an overlay network. The site network is a layer-2 network with independent business functions connected to the core network through one or more edge devices; The established virtual network provides Layer 2 interconnection between site networks, notifies the MAC addresses of all hosts and routers connected to edge devices, and interconnects multiple sites to form a larger Layer ...
