Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0021] When the VTEP device (assumed to be VTEP1) perceives that the VM (assumed to be VM1) is online but does not receive a gratuitous ARP packet within the preset time (that is, VM1 is a silent VM), VTEP1 can set the GW (Gateway, gateway) virtual The host route and MAC address of the interface are synchronized to all peer VTEP devices (such as VTEP2 and VTEP3) as EVPNBGP neighbors; the peer VTEP device generates the corresponding APR after receiving the host route and MAC address of the GW virtual interface synchronized by VTE...

Abstract

The invention provides a data processing method and apparatus. The method comprises the following steps: when a first VTEP device receives flow forwarded by a neighbor VTEP device and an ARP table entry corresponding to a destination IP address of the flow is not queried, carrying out ARP request message flooding on the destination IP address in the station; and if the first VTEP device does not receive an ARP response message of the destination IP address within a first preset time, sending an ARP flooding indication message to a destination neighbor VTEP device, so that the destination neighbor VTEP device carries out the ARP request message flooding on the destination IP address in the station, wherein the ARP flooding indication message carries the destination IP address, and after the ARP response message of the destination IP address is received, the destination neighbor VTEP device synchronizes the ARP table entry corresponding to the ARP response message to the neighbor VTEP device. By adopting the data processing method and apparatus provided by the embodiment of the invention, the ARP message flooding in an IP backbone network can be reduced.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a data processing method and device. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) network is similar to BGP (Border Gateway Protocol, Border Gateway Protocol) / MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) IP (Internet Protocol, Internet Protocol) VPN network structure is similar, in order to realize each site (Site ), the PE (ProviderEdge, service provider network edge) device on the carrier’s backbone network establishes an EVPN instance and connects to each site’s CE (CustomerEdge, user network edge) device, and establishes a neighbor relationship between each PE and MPLS LSP tunnels. [0003] In the EVPN network, when the VM (Virtual Machine, virtual machine) (CE in the EVPN network) goes online, it usually sends a message to the VTEP (VXLAN (virtualExtensibleLocalAreaNetw...
