Embodiment Construction

[0057] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0058] It should be noted that the embodiment of the present invention is applicable to a scenario where a first CE is dual-homed to an EVPN through a first PE and a second PE. The dual-homed CE is between the first CE and the first PE and the second PE. All-Active mode deployment is adopted, that is, the link between the CE and the first PE and the second PE is bundled into an Ethernet trunk. A given VLAN traffic from the CE to the PE ca...

Abstract

Embodiments of the present invention disclose a method, apparatus and system for forwarding a message, which are adapted for the scenario that a customer edge apparatus CE is connected to an Ether Virtual Private Network (EVPN) by way of dual homing through a first provider edge apparatus PE and a second PE. An Ether link is established between the first PE and the second PE. The method includes: establishing, by the first PE, a port isolation group; receiving, by the first PE, the message forwarded by the second PE through the port at the side of the first PE in the Ether link; and forwarding, by the first PE, the message to CEs connected to ports except the port isolation group in the first PE. Using the present invention, the technical problem, i.e., traffic passing back at the customer side during message forwarding in the EVPN network in the prior art, can be effectively solved without changing the current hardware chip design.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method, equipment and system for message forwarding. Background technique [0002] An Ethernet Virtual Private Network (VPN) connects customer sites in different regions through a Multi-Protocol Label Switching (MPLS) bearer network, so that these sites can behave like a local area network (Local Area Network, LAN) works like that. Ethernet Virtual Private Network (EVPN) is an Ethernet VPN technology based on Border Gateway Protocol (BGP) and MPLS. Compared with traditional Ethernet VPNs, EVPN has a big advantage in that it can achieve All -Active mode, that is, customer edge equipment (Customer Edge, CE) multi-homing to multiple provider edge equipment (Provider Edge, PE), the multiple PEs can be called multi-homing PE, between CE and multi-homing PE Deploy a Multi-Chassis Link Aggregation Group (MC_LAG) to bundle the links between CE and multiple PEs into an Ether...
