摘　　要：EVPN作为一种2层VPN技术,通过转发平面与控制平面分离,能够解决传统2层专线组网中的不支持负载均衡、收敛速度慢、存在广播泛洪等问题。通过对比分析EVPN与传统2层VPN技术,介绍了EVPN的技术原理和优势,同时,结合企业用户专线组网需求,进行了业务场景的应用实践。As a Layer2 VPN technology,EVPN can solve the problems of unsupported load balancing,slow convergence,and broadcast flooding in traditional Layer 2 dedicated line networking by separating the forwarding plane from the control plane. It introduces the technical principles and advantages of EVPN through a comparative analysis of EVPN and traditional Layer 2 VPN technologies. In addition,combined with the needs of enterprise user dedicated line networking,the application practice of business scenarios is carried out.
