Problems solved by technology
When considering the addition of AC-side member access or network-side VXLAN tunnel member links, it is inevitable to set many ACL entries, which is not flexible enough in implementation. This "copy-discard" strategy also wastes the replication capability of the switching chip

The present disclosure provides a traffic forwarding control method. The method comprises the steps of: configuring instance members of a virtual private LAN service (VPLS) instance accessed by traffic according to an access mode of the traffic, the VPLS instance comprising a plurality of instance members; and configuring a sub-broadcast domain corresponding to each instance member of the VPLS instance to obtain a corresponding relation among the traffic access mode and the instance members and sub-broadcast domains, wherein the corresponding relation is used for controlling a traffic forwarding chip to carry out traffic forwarding according to the corresponding relation, and in the same VPLS instance, different instance members correspond to different sub-broadcast domains. According to the traffic forwarding control method provided by the invention, multiple packets of the receiving end equipment can be avoided. The traffic forwarding chip is configured, so that the forwarding isolation is easier to realize, the flexibility is higher, and the stability of a network side is easier to realize. The invention further provides a traffic forwarding control device, a traffic forwardingmethod, a chip and a switch.
Description
technical field [0001] The present disclosure relates to the field of switching technologies, and in particular, to a traffic forwarding control method, a traffic forwarding method, a traffic forwarding control device, a traffic forwarding chip, and a switch. Background technique [0002] In the active-active VTEP (VXLAN Tunnel Endpoints, VXLAN tunnel endpoints) networking scenario, the existing technology is to set ACL (Access Control Lists, Access Control List) isolation on a broadcast domain, such as peerlink (peer-to-peer link) to the network side Direction, peerlink to dual-homing AC (Access Controller, access controller) side direction, etc. need to rely on ACL to discard redundant packets to prevent multiple packets from receiving end devices. When considering the addition of AC-side member access or network-side VXLAN tunnel member links, it is inevitable to set many ACL entries, which is not flexible enough in implementation. This "copy-discard" strategy also wastes...
