| 摘 要： | 城域网扁平化演进中，为提高MPLS L3VPN业务接入的可靠性，将OLT设备规划为VRRP分支节点，可能产生回程路由陷阱。提出两种各自独立的回程路由切换方法，一种是基于OLT可达性检测的严格型方法，另一种是基于路由优先级的简化型方法。实验结果表明，回程路由切换时延为2~8 s。上述回程路由切换方法，能有效避免VRRP回程路由陷阱，增强业务可靠性。

| Abstract: | In the process of flattening metropolitan area network,in order to improve the reliability of MPLS L3VPN services,OLT devices can be planned as VRRP branch nodes.This design could probably induce traps of backhaul routes.Two separate methods of switching backhaul routes were proposed.One is a strict method based on checking the reachability of OLT devices,the other is a simplified method based on the priority of routes.The experimental results show that,handover latency is between 2~ 8 s.These proposed methods of switching backhaul routes,can effectively prevent traps of backhaul routes,and improve the reliability of services. |
