Problems solved by technology

That is to say, whether it is standard VRRP or VRRP that implements load balancing, the route that the upstream device forwards the downstream traffic to the client is randomly selected and cannot be uniquely determined. The route of traffic to the client may also be different
However, in the existing technology, in order to ensu

Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The virtual router involved in the method provided by the present invention includes multiple VRRP routing devices, and one of the multiple VRRP routing devices is selected as the master routing device according to the existing method, and the other is used as the backup routing device. After that, configure the virtual IP address of the virtual router as the default gateway IP address of each client in the same network segment (that is, the virtual IP addresses of each VRRP routing device in the virtual router are the same); for example figure 1 As shown, the method provided by the present invention may include:

[0036] Step 101, the master routing device divides the network segment into more than two subnet segments, and assigns a vir...

Abstract

The invention provides a method for realizing VRRP (Virtual Router Redundancy Protocol) flow transmission and routing equipment, wherein the method comprises the following steps: (A) main routing equipment divides a network section into more than two sub network sections, distributes a corresponding virtual MAC (Media Access Control) address to each sub network section and distributes each sub network section and the corresponding virtual MAC address to the routing equipment included in the virtual router; and (B) the routing equipment distributed with the sub network section and the virtual MAC address publishes the sub network section route corresponding to the distributed sub network section to uplink equipment connected with the virtual router. By using the invention, the problem caused by randomly selecting a route forwarding downlink flow from an equivalent route by the uplink equipment is avoided.

Description

technical field [0001] The invention relates to a network communication technology, in particular to a method and a routing device for realizing virtual router redundancy protocol (VRRP: Virtual Router Redundancy Protocol) traffic transmission. Background technique [0002] When realizing the communication between the client and the external network, the same default gateway is usually set for all the clients in the same network segment, that is, the default route with the same gateway as the next hop is configured, and the packets sent by the client to other network segments It will be sent to the gateway through the default route, and then forwarded by the gateway, so as to realize the communication between the client and the external network. However, when the gateway fails, all clients in this network segment that use the gateway as the default route will not be able to communicate with the external network. It can be seen that although the default route provides conven...
