Abstract

The invention provides a message forwarding method and device, and the method comprises the steps: refusing to send a broadcast message through a target port according to a target ACL table item issued by the target port when the broadcast message sent by other PE devices in a redundant backup group is received, wherein the target port is a port, connected with a multi-homing CE device, on the PE device, and the target ACL table item is used for indicating the PE device to refuse to pass through the target port, and forwarding broadcast messages sent by other PE devices in the redundant backup group; and when a broadcast message of the non-multi-homing CE device is received, broadcasting the broadcast message through the CPU. By applying the embodiment of the invention, the broadcast message of the multi-homing CE device can be prevented from forming a loop, the normal forwarding of the message is ensured, and the consumption of ACL resources is reduced.

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 Private Local Area Network Service (VPLS for short) is a Layer 2 Virtual Private Network (VPN for short) technology based on Multi-Protocol Label Switching (MPLS for short) network. [0003] VPLS supports multi-active and multi-homing of Ethernet Virtual Private Network (EVPN), that is, a Customer Edge (CE) device can be connected to multiple service provider network edges through different links. (Provider Edge, referred to as PE) equipment, multiple connected PE equipment form a redundant backup group, which can avoid the single point failure of PE equipment from affecting the network, thereby improving the reliability of the network. [0004] In order to prevent all PE devices in the redundant backup group from sending flooding traffic to multi-homing CE devices, it is necessary to el...
