Problems solved by technology

However, by manually dividing OSPF domains and configuring OSPF domain numbers for each network device, as the network scale continues to expand, the configuration process is cumbersome, consumes a lot of labor costs, and is not reliable enough, prone to configuration errors

Embodiment Construction

[0048]As the number of network devices included in the network and the amount of data generated continue to increase, it becomes very difficult for the network to maintain the link state database of the entire network. Then, according to the definition of the Open Shortest Path First (English: OpenShortest Path First, referred to as: OSPF) routing protocol, a routing domain or an autonomous system (English: Autonomous System, referred to as: AS) can be divided into multiple OSPF domains, Each OSPF domain includes a group of network devices combined according to certain OSPF routing rules. In this way, each OSPF domain only needs to maintain the link state database of the domain separately, and the network devices in the domain unify the routing information by exchanging OSPF messages, and there is no need to maintain the huge link state database of the entire network as a whole. Simplifies network operation and maintenance costs. Moreover, after OSPF domains are divided, on t...

Abstract

The invention discloses a method for sending OSPF domain information and a method and device for obtaining the OSPF domain information. The method comprises the steps that a controller determines corresponding configuration information for each piece of network equipment in a network from a preset resource pool according to an equipment role, LLDP information and a preset OSPF domain division model, wherein the configuration information is information in a preset resource pool, and the configuration information at least comprises an OSPF domain number of the network equipment; and sending, bythe controller, the configuration information to the corresponding network devices. Thus, the controller automatically divides the OSPF domain for each network device through the OSPF domain divisionmodel, and configures corresponding configuration information such as OSPF domain numbers for each network device from the preset resource pool without manually dividing the OSPF domain and configuring the OSPF domain numbers for the network devices one by one, thereby improving the efficiency and reliability of the OSPF domain division process.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for sending OSPF domain information, and a method and device for obtaining OSPF domain information. Background technique [0002] Virtual Extended Local Area Network (English: Virtual Extensible Local Area Network, abbreviated: VXLAN) technology is a network virtualization technology defined by the Internet Engineering Task Force (English: Internet Engineering Task Force, abbreviated: IETF). The VXLAN encapsulates the original message in the User Datagram Protocol (English: User Datagram Protocol, UDP for short), which can expand the layer-2 network in the range of the layer-3 to meet the needs of multi-tenant and other scenarios. [0003] It is understandable that due to the increasing number of network devices and the amount of data generated in the network, it becomes very difficult for the network to maintain the link state database of the entire...
