Abstract

The present application provides a message forwarding method and device. The method is applied to any VTEP in the DR system, including: obtaining the state of the DR port on the peer VTEP belonging to the same DR system as the VTEP; If the state of the DR port on the peer VTEP is UP, search for the local DR port corresponding to the DR port on the peer VTEP; the DR port on the peer VTEP and the local DR port are connected to the same user host The same aggregation interface; set all AC ports configured on the local DR port to prohibit forwarding non-unicast packets; after receiving the VXLAN packet sent by the peer VTEP, if the decapsulated VXLAN packet is a non-unicast packet If the unicast message is received, the non-unicast message is forwarded to other AC ports recorded in the broadcast list except the AC port that is set to prohibit the forwarding of non-unicast message. Loops can be prevented by using the method provided in this application.

Description

technical field [0001] The present application relates to the field of computer communication, in particular to a message forwarding method and device. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN technology. It uses BGP (Border Gateway Protocol, Border Gateway Protocol) on the control plane to advertise routing information, and uses VXLAN (Virtual eXtensible LAN) on the data plane. , scalable virtual local area network) encapsulation to forward user packets. [0003] In order to improve the reliability, it is possible to use such as figure 1 The EVPN networking mode of distributed aggregation shown in the figure. exist figure 1 In the shown network, VTEP11 (VXLAN Tunnel End Point, VXLAN tunnel end point) and VTEP13 can form a DR (Distributed Relay, distributed aggregation) system, and VTEP11 and VTEP13 can be connected through an IPLVXLAN tunnel. DR port 1 (Distributed Relay interface, distribut...
