Message processing method and device

Abstract

Embodiments of the invention disclose a message processing method and device; the method comprises: after receiving, by a first VTEP (Vxlan tunnel end point), a unicast message transmitted by a virtual machine, if no forwarding information corresponding to a target address of the unicast message is found to be stored in locale, forwarding the unicast message to a second VTEP according to preset default forwarding information so that the second VTEP continues to forward the unicast message. It is indicated that there is no need for all VTEPs to store forwarding formation of all virtual machines in the embodiments of the invention, it is only required that one VTEP stores forwarding information of all virtual machines, address space for partial VTEPs in networking is saved, the requirement on the address space for partial VTEPs in networking is lowered, network resources are saved, the cost of VTEPs is reduced, and networking cost is thus reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message processing method and device. Background technique [0002] In the existing EVPN (Ethernet Virtual Private Network, Ethernet virtual private network) network, each VTEP (VXLAN Tunnel End Point, VXLAN tunnel end point, wherein, VXLAN: VirtualeXtensible Local Area Network, extensible virtual local area network) saves Both the MAC address table and the IP forwarding table store MAC (Media Access Control, Media Access Control) address entries and IP address entries corresponding to all virtual machines in the EVPN network. [0003] For the existing EVPN network, each VTEP needs to have enough address space to save the MAC address entries and IP address entries of all virtual machines in the entire network, so as to ensure normal service processing. When the address space is insufficient and it fails to save the MAC address entries and IP address entries of a...

Problems solved by technology

When the address space is insufficient and it fails to save the MAC address entries and IP address entries of all virtual machines, the following problems will occur: When the storage space of the MAC address table of the VTEP is insufficient, the VTEP cannot If the forwarding information corresponding to the destination MAC address of the unicast packet is found in the MAC address table, an unknown unicast packet will be generated at this time, and the unknown unicast packet will be flooded in the entire EVPN network; when the IP forwarding table of the VTEP When the storage space is insufficient, when the VTEP receives a unicast packet, the forwarding information corresponding to the destination IP address of the unicast packet cannot be found in the stored IP forwarding table, and the unicast packet will be discarded at this time

[0004] Therefore, each VTEP in the networking (EVPN network) must have sufficient address space and meet the corresponding performance requirements. Especially when the number of virtual machines in the networking is large, the address space requirements for each VTEP are higher. Its corresponding performance requirements are also higher. Undoubtedly, this limitation brings certain restrictions to the deployment of EVPN network, and the cost of building the network (EVPN network) will be relatively high.
