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 invention relates to a data communication technology. The invention solves the problem that a VRRP (Virtual Router Redundancy Protocol) gateway cannot be automatically repaired when a double-main phenomenon appears in the existing VRRP networking system, and provides a VRRP gateway, a VRRP system and a double-main detection and repair method. According to the technical solution, the state of an opposite-end gateway is detected by a state detection module, and whether the state is a double-main state currently is judged; if the state is a double-main state, all ARPs (Address Resolution Protocols) on self interface are cleared, an ARP is relearned, and a corresponding terminal address is notified to the opposite-end gateway; if the terminal notified by the opposite-end gateway is received, a static route based on the terminal is formed on a communication tunnel, and whether the terminal corresponds to the learnt ARP is judged, if so, the ARP is deleted, otherwise, no processing is performed; and when a VRRP is recovered, the corresponding static route on the tunnel is deleted. The VRRP gateway, the VRRP system and the method have the advantages of shortening the fault repair time and being applicable to a VRRP networking system.

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 ...
