Abstract

The invention discloses a message forwarding method and device. The method comprises the following steps: when a public network channel between first virtual extensible local area network tunnel endpoint VTEP equipment and remote VTEP equipment in a distributed link aggregation group has faults, establishing a first virtual extensible local area network VXLAN (Virtual eXtensible LAN) tunnel according to an acquired address of the remote VTEP equipment, wherein the next hop of the first VXLAN tunnel is the address of second VTEP equipment in the distributed link aggregation group; associating afirst service on the first VTEP equipment with the first VXLAN tunnel; and transmitting a received message of the first service to the remote VTEP equipment through the first VXLAN tunnel. The message forwarding method provided by the invention establishes the new VXLAN tunnel under the condition that the public network tunnel between the first VTEP equipment and the remote VTEP equipment has thefaults, so that normal forwarding of service messages is guaranteed, and the network reliability is provided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method and device. Background technique [0002] VXLAN (Virtual eXtensible LAN, Virtual Extensible Local Area Network) is a layer-2 virtual private network VPN (Virtual Private Network) technology based on IP network and adopting the encapsulation form of "Media Access Control MAC in User Datagram Protocol UDP". The VXLAN technology uses the existing layer-3 physical network as an underlay network, and builds a virtual layer-2 network on top of it, that is, an overlay stacking network. The Overlay network uses the encapsulation technology and the Layer 3 forwarding path provided by the Underlay network to realize the transmission of Layer 2 packets across the Layer 3 network between different sites. [0003] The VXLAN network is divided into a public network and a private network. Devices in the VXLAN private network access the public ne...
