Problems solved by technology

[0003] for example, figure 1 In the shown network, after the multicast data packet sent by the PC is VXLAN-encapsulated at the non-gateway node and reaches the gateway node, the gateway node decapsulates the multicast data packet with VXLAN and finds that the destination MAC address of the multicast data packet is multicast MAC address, and the destination IP address of the multicast data packet is a multicast IP address, according to the normal processing method, the gateway node will perform Layer 3 multicast multicast replication and forwarding on the multicast data packet after VXLAN decapsulation, but Limited to the forwarding logic of the hardware switching chip on the gateway node, even if the hardware switching chip of the gateway node supports Layer 3 multicast forwarding, it cannot implement Layer 3 multicast forwarding, and can only perform Layer 2 multicast data packets after VXLAN decapsulation.

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A general modular switch consists of a main control board (main board), an interface board (I / O board), and a fabric board (fabric board). The main control board is a single board used to implement protocol stack calculation, forwarding table item delivery and control, and device management. The interface board is a single board for implementing data packet forwarding (including internal forwarding and external forwarding). The network board is a single board used to realize the inter-board and inter-chip forwarding of data packets and control packets within the device. Wherein, the chip on the network board only has the message forwarding function, and is used for transferring messages between different interface boards.

Abstract

This application provides a method and device for forwarding multicast data packets across a virtual scalable local area network. In the present invention, the network board of the VXLAN switch no longer uses a chip with only message forwarding function, but uses a chip with forwarding function and entry function, such as the same switching chip as the interface board. In the present invention, the gateway VXLAN switch realizes the three-layer multicast access of two different VXLANs, and the whole process is only executed inside the gateway VXLAN switch without wasting any bandwidth resources, and the wire-speed forwarding of multicast data messages is achieved.

Description

technical field [0001] The present application relates to network communication technology, in particular to a method and device for forwarding multicast data packets across a Virtual Extensible Local Area Network (VXLAN: VirtualeXtensible Local Access Network). Background technique [0002] At present, even if the hardware switching chip of the gateway node supports Layer 3 multicast forwarding, the forwarding logic of the hardware switching chip does not allow Layer 3 multicast forwarding, and can only perform Layer 2 multicast forwarding. [0003] for example, figure 1 In the shown network, after the multicast data packet sent by the PC is VXLAN-encapsulated at the non-gateway node and reaches the gateway node, the gateway node decapsulates the multicast data packet with VXLAN and finds that the destination MAC address of the multicast data packet is multicast MAC address, and the destination IP address of the multicast data packet is a multicast IP address, according to...
