Embodiment 1

[0095] The working process of the VxLAN message and the VxLAN network is introduced above, and the message processing method of the embodiment of the application for solving the above two problems is introduced below, please refer to Figure 5 , Figure 5 It is a diagram of an embodiment of the message processing method of the embodiment of the present application, including the first network device, the second network device and the third network device, and the third network device is connected to the first network device of the first network device via the first link. interface; the third network device is connected to the second interface of the second network device via a second link, the first link and the second link have the same link identifier, and the link identifier is used To identify the first network device and the second network device connected to the third network device through the first interface and the second interface respectively, the method may include...

Embodiment 2

[0200] In the foregoing embodiment, when the third network device sends the first packet to the first network device, the first network device backs up the first packet to the second network device. In addition to this situation, the first network device needs to obtain corresponding control protocol entries from the other party to complete the configuration of its own corresponding protocol entries after recovering from a failure or after the second network device initially goes online (UP).

[0201] The following takes the initial UP of the second network device in the scenario of interaction between the user and the operator's device as an example, as shown in figure 1 As shown, the first network device is PE1, the second network device is PE2, and the third network device is CE1. PE1 is connected to CE1 through the first link, and PE2 is connected to PE2 through the second link. The first interface on PE1 and PE2 The second interface on the network corresponds to the E...

Embodiment 3

[0238] The message processing method of the embodiment of the present application has been introduced above, and the network equipment of the embodiment of the present application is introduced below, please refer to Figure 12 , Figure 12 It is a diagram of an example of a network device in an embodiment of the present application, where the network device can be applied to a dual-active system, and the network device is used as the first network device in the dual-active system, and in the dual-active system, the second The three network devices are connected to the first interface of the first network device via the first link; the third network device is connected to the second interface of the second network device via the second link, and the first link and The second link has the same link identifier, and the link identifier is used to identify that the first network device and the second network device are respectively connected to the A third network device; whe...

Abstract

The present application relates to the field of communication, and in particular to a message processing method and a network device. The method comprises that a third network device is connected to the first interface of a first network device via a first link; the third network device is connected to the second interface of a second network device via a second link, wherein the first link and the second link have the same link identifier, the first network device receives a first message sent by the third network device, and the first message is a control protocol message; the first networkdevice packages the first message into a second message according to a tunnel protocol, wherein the second message includes a link identifier and the first message; and the first network device sendsthe second message to the second network device through a tunnel. The method processes the control protocol message by using the network processor of a forwarding plane, makes a backup of a control plane protocol table entry, and effectively improves the processing efficiency.

Description

technical field [0001] The present application relates to the communication field, and in particular to a message processing method and network equipment. Background technique [0002] In the active-active device scenario, that is, if two network devices that are mutually active-active devices need to synchronize control plane entries, such as Media Access Control (MAC) table, multicast table, and address resolution protocol (ADRP) Address Resolution Protocol, referred to as ARP) tables, etc., need to be synchronized through some control plane protocols, for example, through Ethernet Virtual Private Network (Ethernet Virtual Private Network, referred to as EVPN) protocol to synchronize control plane entries between two network devices The EVPN protocol is a virtual private network (Virtual Private Network, VPN for short) technology used for Layer 2 network interconnection. [0003] For example, two network devices are network device A and network device B. The control plane...
