MAC address learning method and device, equipment and readable storage medium

Abstract

The invention provides an MAC address learning method and device, equipment and a readable storage medium. The method comprises the following steps: when an Ethernet message which is a learning message is received from a message entry, storing the Ethernet message into a message queue through a learning message callback function, and recombining, packaging and sending the Ethernet message to a control plane; converting the Ethernet message in the message queue into an MAC table item through an MAC learning thread, writing the MAC table item into a TCAM, and storing a mirror image of the MAC table item in a memory; enabling the control plane to learn a local MAC through a recombined and packaged Ethernet message, notifying a remote end and sending a local MAC table item to a forwarding plane at the same time, and enabling a forwarding plane adaptation layer to write the local MAC table item into the TCAM and setting a matching action to be in a forwarding state; enabling the aging thread to periodically traverse the mirror image cache of the MAC table item, setting the MAC table item in the pseudo existence state to be in the learning state, and writing the MAC table item in the TCAM. According to the invention, the rate of learning the MAC address of the EVPN service is improved, and the reliability of learning the MAC address of the EVPN service is enhanced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a MAC address learning method, device, equipment and readable storage medium. Background technique [0002] Currently, there are two main ways to learn the local source MAC address: [0003] Method 1: The forwarding chip sends Ethernet packets that need to be learned locally to the control plane to learn the source MAC, and the control plane sends it to the forwarding plane after learning it; Method 2, the forwarding chip learns the source MAC, and the forwarding plane adaptation layer polls Forward the source MAC learned by the chip and send it to the control plane. [0004] Among them, the first method has the following disadvantages: [0005] Repeated sending causes congestion on the signaling channel, some sent messages are discarded, and the control plane processes repeated messages or fails to receive the sent messages, which slows down the learning rate; t...

Problems solved by technology

[0007] The polling of the forwarding adaptation layer is time-consuming; the logic of the forwarding adaptation layer is complex, and polling, duplicate checking, reporting and retransmission are required, and there are performance problems
