Problems solved by technology

[0009] However, among the above two solutions, VRRPE is a proprietary protocol, which needs to modify the packet structure of VRRP, and cannot interoperate with other manufacturers' equipment, and the compatibility is poor; GLBP is also a proprietary protocol, and there are also compatibility issues.

Embodiment Construction

[0046] In view of the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a technical solution for implementing virtual routing redundancy protocol VRRP load sharing, which is applied to VRRP networking. In this technical solution, the layer-2 switch receives the VRRP notification message sent by the router, and maintains a virtual MAC entry according to the VRRP notification message. The corresponding relationship between the virtual MAC address carried and the port that received the VRRP advertisement message; when VRRP receives a message whose destination MAC address matches the virtual MAC address recorded in its own virtual MAC entry, the Layer 2 switch One of the ports corresponding to the MAC address is determined as the outgoing port of the packet, and the packet is forwarded to the corresponding router through the outgoing port.

[0047] Wherein, in the embodiment of the present invention, the routers in the VRRP backup...

Abstract

The invention discloses a method and equipment for realizing VRRP (Virtual Router Redundancy Protocol) load sharing. The method comprises the following steps: receiving a VRRP notification message sent by a router by using a two-layer switch; maintaining a virtual MAC (Media Access Control) table entry according to the VRRP notification message; and when a destination MAC address received by the two-layer switch is matched with the MAC address recorded in the virtual MAC table entry, determining one of the ports corresponding to the destination MAC address as a message export through which the message is forwarded to the corresponding router. According to the invention, under the premise of not changing a current VRRP protocol, the load sharing of the VRRP backup group is realized, the resource utilization rate of the VRRP backup group is improved, and the use compatibility of the scheme is ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for realizing VRRP load sharing. Background technique [0002] The gateway is one of the most important roles in the network world, and the traffic must be forwarded by the gateway to realize the communication between the internal host and the external network. When the gateway fails, internal hosts lose contact with the external network. The gateway provides convenience for the user's configuration operation, but it puts forward high requirements for the stability of the device. In the prior art, the reliability of the system is generally improved by increasing the number of gateways, but how to select a forwarding path among multiple egresses has become an urgent problem to be solved. [0003] In the prior art, VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) technology is usually used to solve the above problems. VRRP can...
