Problems solved by technology

Once the VTEP (VXLAN Tunnel Endpoints, VXLAN tunnel endpoint) in the VXLAN network sets a different destination UDP port number for the VXLAN message, the VTEP cannot recognize that the received VXLAN data message is a VXLAN data message, and the VTEP cannot normally forward the VXLAN data message

Abstract

The invention provides a message forwarding method and equipment. The method comprises: a tunnel endpoint obtaining a destination UDP port number of a VXLAN message set by an opposite tunnel endpoint; recording the obtained target UDP port number in a port number register; the port number register being associated with a VXLAN tunnel identifier connected with an opposite end tunnel endpoint; searching an MAC address table item matched with a destination MAC address of the Ethernet data message to be forwarded; reading VXLAN packaging information, a destination UDP port number and an output port according to the VXLAN tunnel identifier of the MAC address table entry; encapsulating the Ethernet data message to be forwarded into a VXLAN data message based on the VXLAN encapsulation information; setting a target UDP field of an outer UDP header of the VXLAN data message based on the target UDP port number; and sending the VXLAN data message through the output port.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a message forwarding method and device. Background technique [0002] VXLAN (Virtual eXtensible Local Area Network, Virtual Extensible Local Area Network) is a virtualized tunnel communication technology. VXLAN uses tunneling technology on the underlying physical network (underlay), and uses the Overlay logical network constructed by the UDP layer to decouple the logical network from the physical network and realize flexible networking requirements. It has almost no impact on the original network architecture, and a new layer of network can be set up without making any changes to the original network. Similar to Layer 2 VLAN, VXLAN uses VNI (VXLAN Network Identifier, VXLAN Network Identifier) ​​to represent a Layer 2 network. [0003] The encapsulation format of the VXLAN message is: encapsulating an 8-byte VXLAN header, an 8-byte outer UDP (User Datagram Protocol, Us...
