Problems solved by technology

[0004] This method uses the physical properties of PE equipment to bring stability to the system, but it has considerable shortcomings.
First of all, the stacking method itself has certain technical defects, which brings additional instability
Secondly, this stacking technology must physically connect PE devices, which cannot achieve cross-regional disaster recovery
In addition, by issuing the same virtual IP address to provide services, it brings great inflexibility

Abstract

The invention particularly relates to a dynamic disaster recovery method, system and device of a PE device, a medium and a hybrid cloud system. The dynamic disaster recovery method of the PE device comprises: receiving first routing information by first PE device from first CE device, and receiving second routing information by second PE device from second CE device; announcing, by the first PE device, the first routing information to the second PE device, and announcing, by the second PE device, the second routing information to the first PE device; receiving, by the gateway, first routing information from the first PE device and second routing information from the second PE device; when the gateway does not receive the first routing information from the first PE device, switching the gateway to receive the first routing information from the second PE device, and when the gateway does not receive the second routing information from the second PE device, switching the gateway to receive the second routing information from the first PE device. According to the invention, the stability of the PE device can be provided, and meanwhile, the great flexibility of deployment and schedulingis provided.

Description

technical field [0001] The invention particularly relates to a dynamic disaster recovery method, system, equipment, medium and hybrid cloud system of PE equipment. Background technique [0002] In the cloud computing environment, hybrid cloud systems are becoming a new standard. Users connect their own private cloud to the provider's public cloud through a managed private line for hybrid cloud deployment, thus connecting the user's internal private cloud network and the virtual private cloud (VPC, Virtual Private Cloud) on the provider's public cloud. Cloud) network. [0003] Provider Edge (PE, Provider Edge) equipment, as the core forwarding node of the hybrid cloud system, must support the disaster recovery function. Traditional PE devices are usually deployed in the form of Link Aggregation Group (LAG, Link Aggregation Group). Two PE devices are physically stacked and bundled, and one PE device is presented to the outside world, and the same virtual IP address is broadc...
