Embodiment Construction

[0019] Such as figure 1 As shown, it is a schematic diagram of a VXLAN network architecture provided by the embodiment of the present application. A VXLAN network includes multiple VTEPs, such as VTEP1, VTEP2, VTEP3, and VTEP4.

[0020] A VTEP is an endpoint device used to establish a VXLAN tunnel on a VXLAN network, and is used to send and receive VXLAN packets on the VXLAN network. A VTEP can be connected to multiple VXLAN networks, and can also be connected to multiple servers in different or the same VXLAN networks. It should be noted that, when a VTEP is connected to multiple VXLAN networks, different interfaces of the VTEP may correspond to different VXLAN networks, or may correspond to the same VXLAN network.

[0021] The foregoing server refers to a physical server or a virtual machine (Virtual Machine, VM for short). VM refers to a complete computer system with complete hardware system functions simulated by software and running in a completely isolated environment...

Abstract

The present application provides a multicast method and VTEP equipment, which relate to the technical field of data communication and are used to solve the problem of flooding of multicast traffic in a VXLAN network. The method includes: the local VTEP receives the first VXLAN message sent by the remote VTEP; wherein, the first VXLAN message includes: the address of the remote VTEP, the target virtual extended local area network identifier VNI, and the target virtual local area network VLAN identification, and a multicast join message; the multicast join message includes the address of the target multicast group; the local VTEP creates a target multicast forwarding table according to the first VXLAN message, and the remote VTEP The address of the target multicast forwarding table is added to the replication table of the target multicast forwarding table; the target multicast forwarding table is used to make the local VTEP forward the multicast message of the target multicast group to the remote VTEP . This application is applicable to the process of VTEP forwarding multicast packets.

Description

technical field [0001] The present application relates to the technical field of data communication, in particular to a multicast method and VTEP equipment. Background technique [0002] Virtual Extensible Local Area Network (VXLAN) is a network virtualization technology used to provide more Layer 2 network segments to meet the needs of large-scale cloud computing. Currently, VXLAN forwards broadcast, unknown unicast, and multicast (broadcast, unknown unicast, multicast, BUM for short) packets in the same way. Specifically, a VXLAN tunnel end point (VTEP for short) in the VXLAN network creates a BUM replication table according to dynamically learned BUM members or a statically configured BUM member list. After a certain VTEP receives BUM traffic, the VTEP sends the BUM traffic to other VTEPs in the VXLAN network according to the BUM replication table. [0003] However, in a multicast scenario, for a specific multicast group, generally only some VTEPs in the VXLAN network n...
