Embodiment 1

[0077] Such as Figure 5 As shown, CE11 is multi-homing connected to VTEP11 and VTEP12, and VTEP11 and VTEP12 are respectively connected to VTEP13. VM11 is a single-hung device connected to VTEP11, and VM12 is connected to CE11.

[0078] VTEP11 and VTEP12 establish Border Gateway Protocol (BGP, Border Gateway Protocol) neighbor relationship, send Ethernet segment routing information through BGP UPDATE information, and perform DF election;

[0079] VTEP11 becomes the master device through DF election, and VTEP11 releases the MAC address information of all devices connected to CE11 to VTEP12 and VTEP13;

[0080] VTEP12 and VTEP13 receive the MAC address information of all devices connected to CE11 issued by VTEP11, and establish MAC address entries of all devices connected to CE11, with the next hop being VTEP11;

[0081] Add VTEP14, VTEP14 is connected with VTEP13 and CE11;

[0082] VTEP14 sends the Ethernet segment routing information to VTEP11 and VTEP12 through BGP UPDATE...

Abstract

The invention provides a data transmission control method, which is applied to a virtual extensible local area network tunnel endpoint VTEP, and the control method comprises the steps: responding to a preset condition, generating an access control list, wherein the preset condition comprises that the current VTEP is changed from a master device to a slave device, and a single-hanging device connected to the current VTEP, the access control list is used for allowing the single-hanging device to perform data transmission with a target customer edge (CE) through a current VTEP, the target CE is connected to a plurality of VTEPs in a virtual extensible local area network (VXLAN) in a multi-homing manner, and the plurality of VTEPs comprise the current VTEP; and controlling transmission of a data packet to be transmitted according to the access control list. The invention further provides electronic equipment.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a data transmission control method and an electronic device. Background technique [0002] Virtual Extensible Local Area Network (VXLAN, Virtual eXtensible LAN) is a layer-2 virtual private network (VPN, Virtual Private Network) technology based on IP network. Based on the existing service provider or enterprise Internet Protocol (IP, Internet Protocol) network, VXLAN can provide Layer 2 interconnection for dispersed physical sites and provide service isolation for different tenants. Mainly used in data center networks. [0003] In the VXLAN Ethernet Virtual Network (EVN, Ethernet Virtual Network) solution, there is a single-active (Single-Active) mode, the core of which is to reserve only one link for data transmission, and the rest of the links are in a blocked state. The EVN determines the link used for data transmission through Desig...
