Problems solved by technology

[0005] When the number of MAC addresses is large, when edge device A sends all learned MAC addresses to edge device B, it will occupy a large amount of network bandwidth and memory of edge device A, and edge device B will receive all MAC addresses from It takes a long time to select a valid MAC address from the addresses

Embodiment Construction

[0039] Aiming at the problems existing in the prior art, an embodiment of the present invention proposes a method for synchronizing MAC addresses. by figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention, and the method is applied to an EVI network including a local edge device and a remote edge device. The local edge device and the remote edge device are relative. When the edge device A is the local edge device, the edge device B is the remote edge device. When the edge device B is the local edge device, the edge device A is the remote edge device. edge device. In the above application scenarios, such as figure 2 As shown, the method for synchronizing the MAC address may specifically include the following steps:

[0040] In step 201, the local edge device receives a first packet from the remote edge device, and the first packet at least carries first extended VLAN information corresponding to the remote edge device.

Abstract

The present invention provides an MAC address synchronization method and device. The method comprises: an edge device at a home terminal receives a first message from an edge device at a remote terminal, and the first message carries first expanded VLAN information; the edge device at the home terminal obtains a first MAC address with respect to the first expanded VLAN information; and the edge device at the home terminal adds the first expanded VLAN information and the first MAC address in a second message, and sends the second message to the edge device at the remote terminal. According to the technical scheme of the invention, the sending quantity of MAC addresses is reduced, the occupation of network bandwidth is minimized and the memory resource is saved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for synchronizing MAC addresses. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of networking of an EVI (Ethernet Virtual Interconnect, Ethernet Virtual Interconnection) network. EVI is a layer 2 VPN (Virtual Private Network, virtual private network) technology based on an IP core network, and can be based on an existing Service provider networks and enterprise networks provide Layer 2 interconnection functions for dispersed physical sites. The switching device at the edge of the site network is an edge device, which operates as a Layer 2 device on the site network and as a Layer 3 device on the core network. [0003] After the edge device A learns the MAC (Media Access Control, Media Access Control) address of the user equipment in the site network 1, it passes the IS-IS (Intermediate System to Intermediate System, ...
