Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0036] In a multi-homing network, when a customer edge device (English: Customer Edge, referred to as: CE) is connected to two or more service provider edge devices (English: Provider Edge, referred to as: PE) through different Ethernet links A collection of these Ethernet links forms an Ethernet segment (English: Ethernet Segment, ES for short), and is identified by the same ESI, and multiple connected PEs form a redundant backup group. In this embodiment of the application, differ...

Abstract

The embodiment of the present application provides an information processing method and device. The first VTEP of the EVPN campus network based on the user identity establishes a connection with The first AC associated with the target client information and the target VXLAN tunnel; if the second VTEP is the local backup device, the first interface is configured with the first ESI, and sends authentication information carrying the target client to the second VTEP, and the first ESI , the first routing message of the target client information and the identifier of the target VXLAN tunnel. The second VTEP establishes the second AC associated with the target client information and the target VXLAN tunnel on the second interface configured with the first ESI according to the first routing message. Applying the embodiments of the present application can solve the problem that the client goes offline and disconnects data when the VTEP fails or the link connecting the client fails, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an information processing method and device. Background technique [0002] Ethernet Virtual Private Network (English: Ethernet Virtual Private Network, referred to as: EVPN) is a layer 2 VPN technology network. The EVPN control plane adopts Multiprotocol-Border Gateway Protocol (English: Multiprotocol-Border Gateway Protocol, referred to as: MP-BGP) to notify EVPN routing messages, and the EVPN data plane adopts scalable virtual local area network (English: Virtual Extensible Local Area Networks, referred to as : VXLAN) to forward packets. [0003] In the EVPN campus network based on user identity, the VXLAN tunnel endpoint (English: VXLAN Tunnel EndPoint, VTEP for short) authenticates the client according to the authentication message sent by the client, and after the authentication passes. VTEP is created on VTEP based on information such as the interfa...
