Abstract

The invention provides a traffic forwarding method and a traffic forwarding device. The method comprises the steps of when the condition that a virtual machine in a switch builds a VPN is detected, mapping the VPN to a hardware VPN according to identification information of the virtual machine; when the condition that the VPN is bound with a VLAN port of the virtual machine in the switch is detected, generating an ACL table item corresponding to the VPN; and then, when traffic matched with the local ACL table item is received, forwarding the traffic according to the ACL table item matched withthe traffic. With the application of the method and the device provided by the embodiment of the invention, isolation of routes between the virtual machines in the switch can be achieved, and the traffic forwarding interference due to the fact that the different virtual machines in the switch have the same IP address, mask and VPN is avoided.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a traffic forwarding method and device. Background technique [0002] At present, in switches that support network board agents, the chips on the network board generally do not support virtualization. When there are IP (Internet Protocol, Internet Protocol) addresses, masks and VPN (Virtual Private Network, Virtual Private Network) are the same, they will interfere with each other when traffic is forwarded. For example, assuming that a route 0.0.0.0 / 0 is configured for both virtual machine 1 and virtual machine 2 in the switch, and the VPN of the route is also the same, then when the network board receives the destination IP address and the mask is 0.0.0.0 / 0 When the traffic is detected, the network board will not be able to determine whether to search for the route of VM 1 to forward the traffic, or to find the route of VM 2 for forwarding.
