Description

一种配置方法、装置及路由器Configuration method, device and router 技术领域Technical field
本文涉及但不限于通信技术领域，涉及一种配置方法、装置及路由器。This document relates to, but is not limited to, the field of communication technology, and relates to a configuration method, device and router.
背景技术Background technique
虚拟专用局域网业务(Virtual Private LAN Service，VPLS)是一种基于网络之间互连的网络协议(IP，Internet Protocol)/多协议标签交换(Multi-Protocol Label Switching，MPLS)和以太网技术的二层虚拟专用网业务，其技术核心思想是利用信令协议在VPLS实例中的运营商边缘路由器(Provider Edge，PE)节点之间建立及维护虚拟连接通道，将二层协议帧封装后在虚拟连接通道上传输、交换，使广域范围内多个局域网在数据链路层面被整合为一张网络，向用户提供虚拟的以太网服务。Virtual Private LAN Service (VPLS) is a network protocol (IP, Internet Protocol)/Multi-Protocol Label Switching (MPLS) and Ethernet technology based on interconnection between networks. Layered virtual private network service, the core idea of which is to establish and maintain a virtual connection channel between the Provider Edge (PE) nodes in the VPLS instance by using the signaling protocol, and encapsulate the Layer 2 protocol frame in the virtual connection. Transmission and exchange on the channel enable multiple LANs in the wide area to be integrated into one network at the data link level to provide virtual Ethernet services to users.
目前，在网络中部署VPLS，有点到点连接(Martini)和点到多点连接(Kompella)两个主要的技术流派。Martini方案是一种点对点的二层虚拟专用网络(L2VPN，Layer2 Virtual Private Network)解决方案，更多的操作需要手工完成，而Kompella方案引入了边界网关协议(Border Gateway Protocol，BGP)作为虚拟专用网络(VPN)的自动发现机制，具有更好的拓展性。Currently, VPLS is deployed in the network, with a few bit-to-point connections (Martini) and point-to-multipoint connections (Kompella). The Martini solution is a peer-to-peer Layer 2 Virtual Private Network (L2VPN) solution. More operations need to be done manually. The Kompella solution introduces the Border Gateway Protocol (BGP) as a virtual private network. (VPN) automatic discovery mechanism, with better scalability.
然而，Kompella方案是基于实例级别来配置的，所有虚拟连接通道均动态生成，在虚拟连接通道级别上的精细化控制，例如隧道策略、性能统计、双向转发侦测(Bidirectional Forwarding Detection，BFD)等功能，在相关的标准和草案中并没有涉及，因此，目前的路由器设备中，对于Kompella方案的VPLS，并不支持基于虚拟连接通道级别上的精细化控制，包括伪线(Pseudo Wire，PW)的隧道策略、性能统计、BFD等功能。However, the Kompella solution is configured based on the instance level. All virtual connection channels are dynamically generated, and fine-grained control at the virtual connection channel level, such as tunneling policy, performance statistics, Bidirectional Forwarding Detection (BFD), etc. The function is not covered in the relevant standards and drafts. Therefore, in the current router equipment, the VPLS of the Kompella scheme does not support fine-grained control based on the virtual connection channel level, including Pseudo Wire (PW). Tunneling strategy, performance statistics, BFD and other functions.
