Embodiment Construction

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0023] An embodiment of the present invention proposes a method for transmitting a message in a VRRPE, which is applied to an MFF networking, and the networking includes an MFF device and a VRRPE device.

[0024] see image 3 , image 3 This is a flowchart of a method for transmitting a packet in VRRPE in an embodiment of the present invention. Specific steps are as follows:

[0025] Step 301, the MFF device intercepts the ARP request message sent by the attached client, records the information of the request message, modifies the destination IP address of the request message to the gateway IP address, and sends it to the VRRPE device. the main device.

[0026] The information of the request packet recorded in t...

Abstract

An MFF device intercepts an ARP request message sent by a client connected to the MFF device and forwards the ARP request message to a main device of the VRRPE devices. When the MFF device intercepts a response message which is sent by the main device of the VRRPE devices and takes a virtual MAC address assigned by the main device according to a load balancing algorithm as a source MAC address, the MFF device sends the ARP response message to the client.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for transmitting messages in VRRPE. Background technique [0002] In the traditional Ethernet networking solution, in order to achieve Layer 2 isolation and Layer 3 intercommunication between different client hosts, the method of dividing VLANs on switches is usually adopted. However, when there are many users who need Layer 2 isolation from each other, this method will occupy a lot of VLAN resources; at the same time, in order to achieve Layer 3 interoperability between clients, it is necessary to plan different IP network segments for each VLAN, and configure VLANs The IP address of the interface, so dividing too many VLANs will reduce the efficiency of IP address allocation. [0003] In order to improve this situation, a solution is provided, which implements Layer 2 isolation and Layer 3 intercommunication between client hosts in the...
