Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manual configuration process for VXLAN networks is inefficient and error-prone, especially in large-scale networks, leading to low configuration efficiency and a high error rate.
Innovation Solution
A method for automatic VXLAN configuration using GRASP information and ANIMA protocol, where network devices autonomously establish VXLAN tunnels based on configuration information, eliminating the need for manual intervention and centralized management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration is used for VXLAN tunnels, then configuration flexibility and control are maintained, but configuration efficiency decreases and error rate increases
Solution Approach 1:
The patent implements self-service by enabling network devices to automatically discover and configure VXLAN tunnels through GRASP protocol exchanges. Devices autonomously generate configuration information, establish tunnels with peer devices, and manage their own VXLAN instances without manual intervention, thereby dramatically improving configuration efficiency while maintaining control through standardized protocols
Solution Approach 2:
The patent applies preliminary action by having devices pre-generate and exchange GRASP configuration information before actual VXLAN tunnel establishment. The configuration data including VNI, tunnel endpoints, and routing parameters is prepared in advance through structured GRASP messages, enabling rapid automated tunnel creation without manual configuration steps
2Loss of time
If manual configuration is performed for each device individually, then precise control over each device is achieved, but time consumption increases significantly
Solution Approach 1:
The patent merges individual device configuration operations into a unified automated process. Multiple devices simultaneously exchange GRASP configuration information and establish VXLAN tunnels through coordinated protocol exchanges, transforming sequential manual configuration into parallel automated operations that reduce total configuration time while maintaining individual device control through standardized message exchanges
3Reliability
If manual VXLAN configuration is implemented across multiple devices, then configuration accuracy can be monitored, but error rate remains high due to human factors
Solution Approach 1:
The patent implements feedback mechanisms through GRASP protocol exchanges where devices verify configuration information mutuality, confirm tunnel establishment status, and report configuration states. This automated feedback loop ensures configuration accuracy by validating parameters such as VNI matching, endpoint reachability, and tunnel operational status without human intervention, thereby improving reliability while enabling automation

AI summary
A VXLAN configuration method, a device, and a system are provided. The method includes the following: A first network device obtains configuration information, generates first GRASP information based on the configuration information, and sends the first GRASP information to a second network device, where the configuration information includes VTEP device information, a plurality of pieces of VTEP device information are respectively used to indicate a plurality of VTEPs included in a VXLAN, the first GRASP information includes objective information, and the objective information is used to carry the configuration information. The second network device receives the first GRASP information, and establishes a VXLAN tunnel based on the first GRASP information. In this way, automatic VXLAN configuration is implemented, and existing problems of low VXLAN configuration efficiency and a relatively high error rate are avoided.
