Problems solved by technology

[0006] When a new router joins the VRRP backup group, the Master router assigns it a new virtual MAC. However, since the TCP handshake running on the server is not interrupted at this time, the server will not actively trigger the ARP request, resulting in the traffic of the current server Unable to share to newly joined router

Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] In existing implementations, the devices that join the VRRP backup group can be routers or layer-3 switches. In the present invention, the devices that can join the VRRP backup group are collectively referred to as layer-3 processing devices.

[0022] Taking routers as an example to join the VRRP backup group, the method for implementing VRRP load balancing in the present invention will be described in detail below, and its implementation principle is also applicable to layer-3 switches.

[0023] see figure 2 , figure 2 It is a flow chart of the VRRP load balancing method in the embodiment of the present invention, the method is applied to the Master router in the VRRP backup group, and the method includes:

Abstract

The present invention provides a VRRP load balancing method and device. The technical solution is: when a new three-layer processing device joins a VRRP backup group, the Master device allocates a virtual MAC address for the new three-layer processing device and notifies the VRRP backup group Create a VF corresponding to the virtual MAC address in each member device; obtain the service traffic of each server forwarding business via the VRRP backup group, and allocate a group of servers for the virtual MAC address based on the business traffic of all servers forwarding business via the VRRP backup group , notifying the group of servers of the virtual MAC address, so that the VF corresponding to the virtual MAC address forwards the services of the group of servers.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a VRRP load balancing method and device. Background technique [0002] The Virtual Router Redundancy Protocol (VRRP for short) is a routing protocol proposed by the IETF to solve the single-point failure phenomenon of static gateways configured in LANs. VRRP divides a group of routers in the LAN together, which is called a backup group. The backup group consists of a Master router and multiple Backup routers, which is functionally equivalent to a virtual router. In VRRP standard protocol mode, only the master router in the VRRP backup group can forward packets, and the backup router is in the listening state and cannot forward packets. [0003] On the basis of VRRP standard protocol mode, VRRP load balancing mode adds load balancing function. Its realization principle is as follows: one virtual IP address corresponds to multiple virtual MAC addresses, and each router in ...
