Route filtering method, device, electronic device and computer-readable storage medium

Abstract

The present invention relates to a routing filtering method, device, electronic equipment and computer-readable storage medium. The core equipment obtains and saves the routing message notified by the branch device, and when it is determined that there is a notification group corresponding to the network identifier included in the routing message , add the device ID included in the routing message to the corresponding notification group; then the core device notifies the routing message to the remaining device IDs included in the corresponding notification group through the routing table corresponding to the routing ID included in the routing message branch device. In this process, the core device only has the query action of matching the notification group, and only traverses the branch devices corresponding to other device identification members in the corresponding notification group. For branch devices, and each neighbor requires a query match, 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
