Abstract

The invention relates to a message forwarding method and device. The method includes: receiving a tunnel switching command, including an identifier of the first VSI and an identifier of the first VXLAN tunnel; acquiring the tunnel interface status of the first VXLAN tunnel in the first VSI according to the identifier of the first VSI and the identifier of the first VXLAN tunnel and the tunnel interface status of the second VXLAN tunnel; if the tunnel interface status of the first VXLAN tunnel in the first VSI is valid and the tunnel interface status of the second VXLAN tunnel is blocked, then the first VXLAN tunnel in the first VSI switch the state of the tunnel interface of the second VXLAN tunnel to the blocked state, and switch the state of the tunnel interface of the second VXLAN tunnel to the valid state; replace the egress port corresponding to the first VSI in the forwarding table stored in the VTEP from the identifier of the first VXLAN tunnel to the first 2. The identifier of the VXLAN tunnel. The VTEP can flexibly select the VXLAN tunnel used to forward service packets in the VSI.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] Virtual Extensible Local Area Network (English: Virtual Extensible Local Area Network, referred to as: VXLAN) is based on the network protocol (English: Internet Protocol, referred to as: IP) network, using the media access control to encapsulate the user datagram protocol (English: Media Access Control in User Datagram Protocol, referred to as: MAC in UDP) encapsulation form of the two-layer virtual private network (English: Virtual Private Network, referred to as: VPN) technology. VXLAN is mainly used in data center networks. It can provide Layer 2 interconnection for scattered physical sites based on existing service provider or enterprise IP networks, and can provide business isolation for different tenants. [0003] In related technologies, the reliability of the VXLAN network for the trans...
