Routing filtering method and device, electronic equipment and computer readable storage medium

Abstract

The invention relates to a route filtering method and device, electronic equipment and a computer readable storage medium. The method comprises the steps: enabling core equipment to obtain and store aroute message notified by branch equipment, and adding an equipment recognition contained in the route message to a corresponding notification group when determining that there is a notification group corresponding to a network recognition contained in the route message; and then the core device notifies the routing message to the branch devices corresponding to the rest device identifiers included in the corresponding notification group through the routing table corresponding to the routing identifier included in the routing message. In this process, the core equipment only performs the query action of matching the notification group and only traverses the branch equipment corresponding to other equipment recognition parts in the corresponding notification group, so that compared with the prior art that the core equipment traverses all the branch equipment establishing the neighbor relationship with the core equipment and each neighbor needs one query matching, the filtering efficiency can be improved.

Description

technical field [0001] The present application belongs to the communication field, and in particular relates to a route filtering method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The network topology of the data center running in the VXLAN (Virtual Extensible Local Area Network) + EVPN (Ethernet Virtual Private Network) network environment mostly adopts the SPINE-LEAF structure (leaf-spine structure), including core equipment and branch equipment connected to the core equipment. Each branch device establishes a neighbor relationship with and only with the core device. In addition to the central node role of IP forwarding, the core device also needs to take on the role of EVPN route reflector. [0003] Each branch device sends a route to the core device, and the core device records the route and reflects the route to other branch devices. However, different tenants are connected to each branch device, and only the same...

Problems solved by technology

However, in actual deployment, the core device advertises indiscriminately, which wastes a lot of resources and occupies network bandwidth. Therefore, when the core device reflects the route, it needs to filter the route, that is, send the route to the branch that needs to obtain it. equipment

[0004] In the traditional filtering method, the core device needs to traverse all the branch devices that have established a neighbor relationship, and then filter based on each neighbor, and the filtering efficiency is low
