Abstract

The embodiments of the invention provide a method for determining a route in a virtual network. The method comprises the following steps that: provider edge (PE) equipment obtains a virtual network forward (VNF) corresponding to one user identifier, wherein the VNF includes a corresponding relation between a destination address prefix of a virtual network and a virtual interface of the PE equipment; and according to the VNF and a corresponding relation between the virtual interface of the PE equipment and a channel identity (ID), the PE equipment generates a virtual route forward (VRF) corresponding to the user identifier, wherein the VRF includes a corresponding relation between the destination address prefix of the virtual network and the channel ID. According to the embodiments of the invention, the PE equipment obtains the VNF corresponding to the user identifier and then generates the VRF corresponding to the user identifier based on the VNF, so that a data packet corresponding to the user identifier can be forwarded according to a route designated by the VRF and thus the user can plan the route by himself.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a method for determining a route in a virtual network and an operator edge device. Background technique [0002] The core idea of ​​network virtualization technology is to realize the coexistence and mutual independence of multiple virtual networks on the same shared physical infrastructure. Each virtual network (Virtual Network, VN) is a collection of virtual nodes and virtual links in the network virtualization environment. Network virtualization technology allows the dynamic creation of multiple heterogeneous virtual networks that coexist on the same physical network and are independent of each other. [0003] A virtual private network (Virtual Private Network, VPN) technology is a commonly used network virtualization technology. In VPN technology, there is one public network routing and forwarding table and multiple user VPN routing and forwar...
