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 , 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 2 forwa...
