Embodiment

[0041] A kind of VRRP gateway in the embodiment of the present invention, its system block diagram sees figure 2 , including a VRRP processing module, a tunnel establishment module, a state detection module and a static route generation module.

[0042] Among them, the VRRP processing module is used to run the VRRP protocol, and specify its own heartbeat address, publish its own heartbeat address through the network, and receive the heartbeat address of the peer gateway. When the peer gateway VRRP message can be received normally, it is normal Run the VRRP protocol without other processing. When the VRRP timer expires and no VRRP message from the peer gateway is received, process it according to the VRRP protocol, keep or switch to the VRRP master device, and notify the status detection module to detect the VRRP status of the peer gateway , receive the notification sent by the status detection module, if it is not currently in the dual-master state, then maintain the current ...

Abstract

The present invention relates to data communication technology. The present invention solves the problem that in the existing VRRP networking system, when a dual-master phenomenon occurs, the VRRP gateway cannot be automatically repaired, and provides a VRRP gateway, a VRRP system and a dual-master detection and repair method, and its technical solution can be summarized as : Use the state detection module to detect the status of the peer gateway to determine whether it is currently in the dual-master state. If it is in the dual-master state, clear all ARP on its own interface and re-learn ARP, and notify the corresponding terminal address to the peer gateway. After receiving the terminal address notified by the peer gateway, a static route based on the terminal is formed on the communication tunnel, and it is judged whether the terminal address corresponds to the learned ARP. If so, the ARP is deleted; otherwise, it is not processed. When VRRP If the protocol is restored, delete the corresponding static route on the tunnel. The invention has the beneficial effects of shortening the fault recovery time and being suitable for VRRP networking systems.

Description

technical field [0001] The invention relates to a data communication technology, in particular to a technology for automatic repair when a network is abnormal in a VRRP protocol (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol). Background technique [0002] At present, some customers still use VRRP networking at the access level. However, for the sake of simplicity, VRRP networking often connects the interfaces of two Layer 3 switches or all-in-one machines (VRRP gateways) in series, and other interfaces are directly connected to terminals. , the schematic diagram of its networking system can be found in figure 1 , which includes two VRRP gateways, which are respectively recorded as the first VRRP gateway N1 and the second VRRP gateway N2. The two VRRP gateways are interconnected, and also include a plurality of terminals, and each terminal is only connected to one VRRP gateway one by one. It can be seen that in the VRRP gateway, the interconnection ...
