Problems solved by technology

[0003] However, in practical applications, since it is necessary to allocate a sub-interface for each VRF on the PE device in the DC, and then bind the allocated sub-interface with the corresponding VRF, there are the following problems: when adding a new tenant, you need to Allocating a new sub-interface on the DC-side PE device occupies more interface resources of the DC-side PE device, and the corresponding configuration process is complicated

Embodiment Construction

[0048] Embodiments of the present invention provide a packet processing method, device, and system, so as to simplify the configuration of PE devices in the DC in a business scenario in which a DC and a site in a virtualized network communicate. In addition, by extending the BGP protocol, the VTEP address can be automatically updated and learned into the corresponding VRF table, further simplifying the configuration process.

[0049] The technical solutions of the present invention are illustrated below through specific examples.

[0050] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the implementation described below Examples are only some embodiments of the present invention, but not all embodiments. Based on t...

Abstract

The invention discloses a message processing method, equipment and a system. The method comprises the following steps: PE (provider edge) equipment receiving a first VxLAN (virtual extensible local area network) encapsulating message sent by NVE equipment, wherein the PE equipment and the NVE equipment are located in the same DC (data center), and the first VxLAN encapsulating message comprises the first VNI (VxLAN network identifier) ; the PE equipment analyzing the first VxLAN encapsulating message, acquiring the first VNI, and acquiring the first VRF (virtual routing forwarding) table corresponding to the first VNI according to the corresponding relation of the VNI and the VRF table; the PE equipment looking up the router in the first VRF according to a destination IP address of the first VxLAN encapsulating message, and forwarding the first VxLAN encapsulating message. Through the adoption of the method disclosed by the invention, the interface resource occupancy can be reduced, and the configuration is simplified.

Description

technical field [0001] The invention relates to network communication technology, in particular to a message processing method, device and system. Background technique [0002] Virtual extensible local area network (Virtual eXtensible Local Area Network, VxLAN) is a technology that encapsulates Layer 2 packets with Layer 3 protocols. The main technical principle of VxLAN is to introduce a MAC-in-UDP format encapsulated packet. That is, by encapsulating the Ethernet frame in a User Datagram Protocol (UDP) message for transmission, the Ethernet frame can be transmitted in the layer-3 network, so that the layer-2 network can be extended in the layer-3 range. In the virtual network interworking business scenario between a data center (DataCenter, DC) and a site, the DC provides virtual machine (Virtual Machine, VM) services for multiple enterprises, and hosts at the site communicate with VMs in the DC through a VxLAN tunnel. In terms of implementation, the Provider Edge (PE) de...
