Method and device for configuring network equipment in multiple DCs

Abstract

The invention provides a network equipment configuration method and device in multiple DCs. The method comprises steps of enabling the SDN controller to determine whether an intercommunication vRouteris created in Border equipment in the first DC or not according to an intercommunication instruction when the SDN controller receives the intercommunication instruction used for instructing the firstvRouter in the first DC and the second vRouter in the second DC to perform service intercommunication; if the intercommunication vRouter has been created, issuing a first configuration instruction tothe Border device, wherein the first configuration instruction comprises a network mapping instruction and a binding instruction; and sending the network mapping instruction to the Border device, sothat the Border device configures a mapping relationship between the VLAN identifier and the VXLAN tunnel identifier on the interworking vRouter according to the network mapping instruction, and bindsthe VPN identifier to which the interworking vRouter belongs with the VXLAN tunnel identifier according to the binding instruction.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for configuring network equipment in a multi-DC. Background technique [0002] The control plane in the EVPN (Ethernet Virtual Private Network, Ethernet private network) network is mainly managed by the SDN (Software Defined Network, software-defined network) controller. The SDN controller can be used to control the virtual Overlay network and carry the Overlay network on the DC (Internet Data Center, data center) physical network, and provide users with on-demand distribution of the Overlay network. [0003] In the Overlay network, in order to meet the intercommunication between tenants in different DCs, SDN controllers are usually used to achieve intercommunication requirements. However, in related technologies, when the virtual router vRouter of a local tenant needs to establish multiple cross-DC intercommunication services At this tim...

Problems solved by technology

[0003] In the Overlay network, in order to meet the intercommunication between tenants in different DCs, SDN controllers are usually used to achieve intercommunication requirements. However, in related technologies, when the virtual router vRouter of a local tenant needs to establish multiple cross-DC intercommunication services At this time, the SDN controller in the DC usually generates a corresponding interworking vRouter for each interworking service and configures a corresponding VPN (Virtual Private Network, virtual private network), which causes the vRouter of the same local tenant in the border device to occupy A large number of VPN resources, and the interaction of routing information between each interworking vRouter will also cause information redundancy
