Problems solved by technology

However, when the EVPN access device works in gateway mode, it is necessary to add gateway-related configurations, such as VPN (Virtual Private Network, virtual private network) configuration information, VSI-IF (Virtual Switch Interface, virtual switch interface) and gateway IP address, etc., which will occupy The EVPN access device has limited ACL (Access Control List, access control list) resources. If there are many virtual machines online in EVPN, it cannot be guaranteed that the EVPN access device has enough resources to store forwarding entries, which will affect the data forwarding performance.

Abstract

The disclosure provides a method and system for controlling a gateway mode, an SDN controller and an access device, and relates to the technical field of the Internet. The SDN controller listens to the upper limit alarm information and alarm release information of the access device; if it receives the upper limit alarm information, it transfers the three-layer forwarding configuration information of the virtual router on the access device to the border gateway, so that the access device is transferred from the gateway The mode is switched to non-gateway mode; if the alarm release information is received, the layer-3 forwarding configuration information of the virtual router corresponding to the access device is restored from the border gateway to the access device, so that the access device is switched from non-gateway mode to gateway mode . Through the above technologies, the forwarding process of the three-layer cross-network segment traffic is effectively guaranteed, and the overall data forwarding performance is improved.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a method and system for controlling a gateway mode, an SDN controller and an access device. Background technique [0002] EVPN (Ethernet Virtual Private Network) is a Layer 2 VPN technology. The control plane uses MP-BGP (MultiProtocol-Border Gateway Protocol, a multi-protocol compatible border gateway protocol) to advertise EVPN routing information, and the data plane uses VXLAN (Virtual eXtensible LAN, extensible virtual local area network) encapsulation mode forwards packets. When the tenant's physical sites are scattered in different locations, EVPN can provide Layer 2 interconnection for the same subnet of the same tenant; at the same time, it can provide Layer 3 interconnection for different subnets of the same tenant through the EVPN gateway, and provide tenants with external networks. Three layers of interconnection. [0003] The EVPN networking struct...
