Problems solved by technology

However, in the existing multi-member device edge device group, in order to avoid Layer 2 message loops between member devices, member devices in the same edge device group are prohibited from synchronizing routing information with each other, resulting in the same edge device Hosts directly connected to different member devices in the group cannot communicate with each other, which limits the functions of member devices
E.g, figure 1 In the shown network, in order to avoid Layer 2 loops between member device D1-1 and member device D1-2, mutual EVPN route advertisement between member device D1-1 and member device D1-2 is disabled, resulting in VM3 connected to D1-1 cannot communicate with VM4 connected to D1-2

Abstract

The present application provides a route synchronization method and device, which are applied to member devices in an edge device group including at least two member devices. By configuring a dedicated first VXLAN on the member devices in the edge device group, the member devices can mutually transmit routing information carrying a specific preset notification identifier to each other in the firstVXLAN, so that the member devices in the edge device group can notify each other of a route. The method and device solve the problem in the prior art that hosts directly getting access to different member devices of the edge device group cannot communicate with each other.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular, to a route synchronization method and device. Background technique [0002] In many current communication systems, the communication between communication devices is realized through a virtual extended local area network (Virtual Extensible LAN, referred to as VXLAN). interconnection and interconnection between different communication systems. On the network edge of the communication system, a device used for data forwarding between the communication system and other communication systems is called an edge device (Edge Device, ED for short). In a relatively large communication system (such as a data center), in order to improve the reliability or fault tolerance of communication, the edge device can be set as an edge device group including two or more member devices, and the member devices in the edge device group Jointly realize the functions of edge ...
