Abstract

The invention provides a route injection method and device. The method comprises the following steps: receiving a network configuration Netconf message which is sent by a Controller and carries destination route information and equipment identification information corresponding to the destination route information which is obtained through route computation by the Controller according to an external route learned through an IBGP neighbor, and sending the destination route information to core equipment or R equipment according to the equipment identification information corresponding to the destination route information. Through an application of the route injection method and device, equipment in a user network can prevent upgrading operation, the number of equipment capable of being accessed is increased, and forwarding performance is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a route injection method and device. Background technique [0002] SDN (Software Defined Network) is a new type of network architecture and a way to realize network virtualization. Its core idea is to separate the control plane of network equipment from the data plane, so as to realize the flexibility of network traffic. control, making the network as a conduit smarter. [0003] In the SDN network using Netconf (a network configuration based on XML (Extensible Markup Language, Extensible Markup Language)) protocol and BGP-LS (Border Gateway Protocol with Link State, border gateway protocol with link state), core Establish an EBGP (External Border Gateway Protocol) neighbor between the device (user core device) and the ISP (Internet Service Provider, Internet Service Provider) device, and establish a neighbor between the core device and the controller (controller, t...
