Problems solved by technology

[0003] In an EVPN network, when the access device supports multiple VPNs, different VPNs are not allowed to have overlapping network segments. Once overlapping network segments exist and the VPNs corresponding to the overlapping network segments communicate with each other, data packets cannot be transmitted normally.
For example, if the access device supports VPN1 and VPN2, VPN1 and VPN2 communicate with each other, VPN1 has network segments 10 and 11, and VPN2 has network segments 11 and 12, since the network segment 11 of VPN1 is the same as the network segment 11 of VPN2, Therefore, if host 1 under network segment 10 of VPN1 accesses host 2 under network segment 11 of VPN2, if the host route of host 2 does not exist in the routing table of VPN1, the data packet cannot be transmitted to host 2, thus Resulting in the failure of normal transmission of data packets
[0004] At present, with the continuous expansion of the network scale, more and more network segments need to be configured, and user configuration errors are prone to occur, resulting in overlapping network segments of different VPNs, which in turn leads to the failure of normal transmission of data packets

Abstract

The present invention provides a data message transmission method and device. The method comprises the following steps: receiving a first data message sent by a first host in a first VPN to a second host; if it is determined that a destination IP address of the first data message hits a segment route of the first VPN, sending a first ARP (Address Resolution Protocol) request to a controller; receiving a second data message issued via the controller and a network identifier corresponding to a second VPN, and determining the second VPN corresponding to the second host according to the network identifier; and if it is determined that the destination IP address of the second data message hits the segment route of the second VPN, sending a second ARP request through an outcoming interface corresponding to the second VPN. Through the technical scheme of the present invention, even if an error occurs in user configuration, resulting in overlapped segments in different VPNs, normal transmission of the data message can be still guaranteed and transmission abnormality caused by overlapped segment problems is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data packet transmission method and device. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN (Virtual Private Network, Virtual Private Network) technology, and the control plane can use MP-BGP (MultiProtocol Border Gateway Protocol, Multi-Protocol Border Gateway Protocol) notification EVPN routing information, while the data plane can use VXLAN (Virtual eXtensible Local Area Network, extensible virtual local area network) to encapsulate data packets. In an EVPN network, when the physical sites of tenants are scattered in different locations, based on the existing service provider network or enterprise IP network, Layer 2 interconnection can be provided for the same network segment of the same tenant, and different The network segment provides Layer 3 interconnection. [0003] On an EV...
